"Salah satu mekanisme terjadinya resistemi leptin pada obesitas adalah kelainan reseptor leptin (Ob-R). Beberapa penelitian membuklikan bahwa aktifitas ikatan leptin di serum manusia berhubungan dengan reseptor leptin terlarut (soluble leptin receptor) dan restriksi asupan energi menyebabkan penurunan kadar leptin darah. Penelitian ini adalah untuk mengetahui beda kadar reseptor leptin terlarut serum dan densitas reseptor leptin dijaringan lemak adventitial aorta setelah dilakukan restriksi diet selama 4 minggu. Kadar reseptor leptin terlarut diukur dengan ELISA dan densitas reseptor leptin di jaringan lemak dengan irnunohistokimia. Kadar reseptor leptin terlarut pada kelompok perlakuan 40% diet normal lebih rendah dibanding kontrol (p=0,02). Tidak didapaikan perbedaan reseptor leptin terlarut yang bermakna antara kelompok perlakuan 40% diet normal, 1 hari puasa-1 hari makan normal dan 1 hari pitasa-2 hari makan normal. Di sisi lain, densitas reseplor leptin dijaringan lemak advenlitia aorta justru lebih tinggi pada kelompok restriksi 40% daripada kontrol. Restriksi diet 40% kalori normal harian menurunkan kadar reseptor leptin terlarut di serum, tetapi meningkatkan densitas reseptor leptin dijaringan lemak advential aorta tikus. Perubahan ini mungkin merupakan akibat mekanisme up regulation dalani mempertahankan homeostasis. (Med J Indones 2006; 15:145-50)

One of the five possible mechanisms of leptin resistance in human obesity is the defect in the leptin receptor (Ob-R). Evidence has accumulated that leptin-binding activity in human serum is related to a soluble form of the leptin receptor, and restriction of energy intake resulted a decrease in circulating leptin levels. Aim of this study is to examine the difference of serum soluble leptin receptor level and ieplin receptor density in rat adipose tissue of adventitial aorta after four weeks treated with different restricted diets. Soluble leptin receptor level was measured by ELISA and leptin receptor density by using immuno-hisfochemistry. The soluble leptin receptor in group treated with 40% of normal daily calori diet was found significantly lower than control (p = 0.02). There were no any significant differences among group treated with 40 % of normal daily calori diet, "I day fast-] day eat", and "ldayfaxt-2 days eat" groups, and among I day fast-1 day eat", "day fast - 2 days eat" and control groups as well. On the other hand, leptin receptor density in adipose tissues was higher in restricted diet group than control. Diet of 40 % normal daily calorie for 4 weeks decreased soluble leptin receptor level, but increased adipocyte leptin receptor density of the adipose tissue of rat adventitial aorta. These changes may be resulted from an up regulation mechanism in relation with homeostatic maintenance. (Med J Indones 2006; 15:145-50)"

"ABSTRAKPada perempuan pascamenopause diperlukan marka biokimiawi dan klinis pada masa jendela terapeutik yang diharapkan dapat digunakan untuk menapis HKND yang berperan sangat penting dalam menghindari dampak demensia tipe alzheimer setelah terapi hormon. Penapisan HKND dapat dimanfaatkan juga untuk upaya terapeutik HKND pada perempuan pascamenopause dan mencegah perburukan ke dalam kondisi demensia tipe alzheimer. Dilakukan studi potong lintang pada 282 perempuan pascamenopause di Jakarta yang dibagi menjadi 2 kelompok, yaitu kelompok positif dengan HKND dan kelompok tanpa HKND. Pemeriksaan dilakukan pada sejumlah variabel seperti usia, lama menopause, keluhan vasomotor, IMT, kadar FSH, kadar LH, kadar leptin, kadar estradiol, dan status kognitif, kemudian dianalisis secara statistik. Diperoleh nilai FSH yang berhubungan bermakna dengan kejadian HKND p = 0,018 , serta variabel lain seperti nisbah FSH/estradiol p = 0,029 dan nisbah FSH/sOB-R p = 0,011 , sementara variabel lain tidak bermakna. Analisis multivariat menunjukkan nisbah FSH/estradiol adalah variabel yang paling berperan terhadap kejadian HKND, dengan nilai OR 1,15. Berdasarkan kurva ROC didapat nilai titik potong nisbah FSH/estradiol dalam memprediksi HKND adalah 1,94 dengan sensitivitas 66,5 dan spesifisitas 46,8 . Nisbah FSH/estradiol pada perempuan pascamenopause yang menderita HKND yang lebih tinggi secara bermakna dibandingkan dengan kelompok tanpa HKND dikaitkan dengan peran neuron KNDy terhadap peningkatan sekresi GnRH dan rendahnya neurosteroid estradiol di otak perempuan pascamenopause yang berisiko menderita HKND. Nilai nisbah FSH/estradiol > 1,94 dapat digunakan untuk penapis diagnostik HKND pada perempuan pascamenopause.

ABSTRACTBiochemical and clinically important markers are needed in the window therapeutic period for postmenopausal women which are expected to be used as a screening methods for CIND as it is very important in avoiding the effect of dementia associated Alzheimer disease after hormone therapy. CIND screening was also useful for CIND treatment strategies in postmenopausal women and preventing postmenopausal women from impaired cognitive function due to dementia. A cross sectional study included 282 postmenopausal women in Jakarta was done, and subjects were further classified into two groups, with CIND and without CIND. Several related variables such as age, duration of menopause, vasomotor symptoms, BMI, FSH level, LH level, leptin level, estradiol level, and cognitive status, were assessed and analyzed statistically. The prevalence of CIND was significantly correlated with FSH level p 0.018 , along with ratio of FSH levels estradiol p 0.029 and ratio of FSH sOB R p 0.011 , while other variables were not. By multivariate analysis, FSH estradiol ratio of 1.15 was found as the most significant factor with probability of having CIND in postmenopausal women. Using the ROC curve, the ratio threshold of FSH estradiol to predict CIND was 1.94, with sensitivity 66.5 and specificity 46.8 . Level of FSH estradiol ratio in postmenopausal women with CIND was significantly higher than women without CIND, and is related to the role of KNDy neurons that induce the secretion of GnRH, and low level of neurosteroid estradiol in postmenopausal women rsquo s brain with risk of CIND. Ratio of FSH estradiol levels 1.94 could be used for screening methods of CIND in postmenopausal women."

"Sindrom ovarium polikistik (SOPK) diketahui terkait dengan obesitas melalui: resistensi leptin. Salah satu penyebab resistensi leptin adalah defisiensi reseptor leptin (LEPR) dibubarkan. Tujuan dari penelitian ini adalah untuk menentukan ekspresi mRNA dari LEPR. gen dilarutkan pada subjek obesitas dan non-obesitas dengan PCOS dan non-SOPK sertamengetahui korelasi antara ekspresi gen tersebut dengan obesitas dan PCOS. Kecepatan Ekspresi mRNA gen LEPR dalam sampel darah diukur menggunakan metode waktu nyata PCR. Penelitian dilakukan pada 96 subjek dengan empat kelompok sampel, yaitu: PCOS non-obesitas, PCOS bebas obesitas, PCOS obesitas, dan PCOS obesitas. Hasil pengukuran menunjukkan ekspresi mRNA rata-rata dari gen LEPR terlarut di masing-masing kelompok 2,10 x 10-4 ng/μL ± 1,88 x 10-4; 1,27 x 10-4 ng/μL ± 1,31 x 10-4; 1,99x 10-4 ng/μL ± 2,35 x 10-4; dan 1,44 x 10-4 ± 2,21 x 10-4 ng/μL. LEPR. ekspresi gen mRNA terlarut dalam semua kelompok obesitas diketahui lebih rendah jika dibandingkan dengankelompok obesitas (P < 0,05) dan tidak ada perbedaan yang signifikan antara kelompok umum tanpa PCOS dan PCOS (1,69 x 10-4 ± 1,65 x 10-4; 1,71 x 10-4 ± 2,27 x 10- 4, P > 0,05). Studi ini menemukan bahwa penurunan ekspresi mRNA dari gen LEPR yang larut berhubungan dengan obesitas dan tidak berhubungan dengan PCOS.Polycystic ovary syndrome (SOPK) is known to be associated with obesity through: leptin resistance. One of the causes of leptin resistance is dissolved leptin receptor (LEPR) deficiency. The aim of this study was to determine the mRNA expression of LEPR. gene was dissolved in obese and non-obese subjects with PCOS and non-PCOS as well asdetermine the correlation between the expression of these genes with obesity and PCOS. Expression velocity of LEPR gene mRNA in blood samples was measured using real-time PCR method. The study was conducted on 96 subjects with four sample groups, namely: non-obese PCOS, obesity-free PCOS, obese PCOS, and obese PCOS. The measurement results showed the average mRNA expression of the soluble LEPR gene in each group was 2.10 x 10-4 ng/μL ± 1.88 x 10-4; 1.27 x 10-4 ng/μL ± 1.31 x 10-4; 1.99x 10-4 ng/μL ± 2.35 x 10-4; and 1.44 x 10-4 ± 2.21 x 10-4 ng/μL.

This study found that decreased mRNA expression of the soluble LEPR gene was associated with obesity and not associated with PCOS."

"Pada wanita hamil trimester kedua terjadi peningkatan kebutuhan besi. Defisiensi besi yang terjadi pada awal kehamilan akan menjadi anemia defisiensi besi pada akhir kehamilan. Defisiensi besi pada kehamilan dapat menimbulkan komplikasi seperti perdarahan akibat atonia uteri. Akhir-akhir ini dikembangkan parameter baru untuk mendeteksi defisiensi besi yaitu soluble transferrin receptor serum (sTfR) yang diharapkan tidak dipengaruhi oleh adanya inflamasi. Penggabungan parameter kadar feritin dan sTfR menjadi rasio sTfR 1 log. feritin diharapkan lebih baik dalam deteksi defisiensi besi. Pada penelitian secara potong lintang pada 108 wanita hamil primigravida trimester kedua didapatkan proporsi defisiensi besi sebesar 43,5% terdiri dari defisiensi besi tahap I sebesar 31,5% ; defisiensi besi tahap II sebesar 8,3% dan defisiensi besi tahap III sebesar 3,7%. Dijumpai 8 (7,4%) wanita hamil dengan anemia, 4 (3,7%) orang diantaranya disebabkan karena defsiensi besi. Pemeriksaan kadar sTfR menggunakan cara imunonephelometri. Dari hasil penelitian ini didapatkan nilai median kadar sTfR pads wanita hamil tanpa defisiensi besi (n=61) sebesar 1,3 mg/L ( 0,97 - 2,32 mg/L), pada defisiensi besi tahap I (n=34) sebesar 1,6 mg/L ( 0,92 - 3,26 mg/L), pada defisiensi besi tahap II (n=9) ditemukan rentang nilai 1,19 - 2,64 mg/L dan pada defisiensi besi tahap III (n=4) ditemukan rentang nilai 3,03 - 5,16 mg/L. Kadar sTfR pada defisiensi besi tahap I Iebih tinggi dibanding tanpa defisiensi besi, pada defisiensi besi tahap II dan III tampak lebih tinggi dibanding defisiensi besi tahap I. Rasio sTfR / log. feritin pada wanita hamil tanpa defisiensi besi didapatkan nilai median 0,68 (0,46-1,34); defisiensi besi tahap I sebesar 1,26 (0,71-3,54); defisiensi besi tahap II didapatkan rentang nilai 0,94-3,22 dan pada defisiensi besi tahap III sebesar 4,28-14,74. Rasio sTfR 1 log. feritin pada defisiensi besi tahap I Iebih tinggi dibanding tanpa defisiensi besi. Pada 50% wanita hamil didapatkan peningkatan kadar CRP. Kadar sTfR pada kadar CRP meningkat maupun normal tidak ditemukan adanya perbedaan yang bermakna. Kadar feritin dan sTfR ditemukan korelasi negatif dengan kekuatan sedang (r = - 0,676; r2 = 0,46); dan sebesar 46% penurunan feritin yang disertai dengan peningkatan kadar sTfR. Pada 47 wanita hamil dengan defisiensi besi ditemukan 19% subyek dengan peningkatan kadar sTfR, sedangkan peningkatan rasio sTfR 1 log. feritin dijumpai pada 55% subyek. Penghitungan rasio sTfR / log. feritin lebih baik dibandingkan hanya memakai kadar sTfR saja dalam hal mendeteksi defisiensi besi. Disarankan untuk melakukan penelitian lebih lanjut untuk membuktikan bahwa rasio sTfR 1 log. feritin yang lebih sensitif dalam hal mendeteksi adanya defisiensi besi, dengan memakai pemeriksaan baku emas untuk mengetahui cadangan besi yaitu pemeriksaan cadangan besi di dalam sum-sum tulang.

In the pregnant women second trimester, the iron demand is increased. Iron deficiency that occurs in the early pregnancy can develop to be iron deficiency anemia. One of the complications of iron deficiency in pregnant women is bleeding due to atonia uteri. Recently there is a new parameter for detection iron deficiency, i.e. soluble transferring receptor serum (sTfR), which is not influenced by inflammation process. We hope that the use of ratio sTfR/ log. feritin will be better than sTfR alone in the detection of iron deficiency. This is a cross sectional study, with 108 pregnant women who were in the second trimester of their 1 6' pregnancy, as subjects. The proportion of iron deficiency is 43,5%; 31,5% had level I iron deficiency; 8,3% had level II iron deficiency and 3,7% was level III. We found 8 (7,4%) pregnant women with anemia; 4 (3,7%) was caused by iron deficiency. We measure sTfR level by immunonephelometry. The result of this research showed that the median of sTfR level in pregnant women without iron deficiency (n=61) was 1,3 mg/L (0,97 - 2,32 mg1L); level i iron deficiency (n=34) was 1,6 mg1L (0,92 - 3,26 mg1L). The range of sTfR value in level II was 1,19 -2,64 mg1L and in the level III (n=4) was 3,03 - 5,16 mg/L. The sTfR level in level I iron deficiency was higher than in pregnant women without iron deficiency. in level II and Ill sTfR was apparently higher than level I iron deficiency. Soluble transferring receptor 1 log. feritin ratio in pregnant women without iron deficiency (n=61) the median value was 0,68 (0,46 -1,34); in the level I iron deficiency (n=34) was 1,26 (0,71 - 3,54). The range in level II iron deficiency was 0,94 - 3,22 and in level III iron deficiency was 4,28-14,74. The sTfR 1 log. feritin in the level I iron deficiency was higher than without iron deficiency. In this research we found that CRP level were increased in 50% subjects. The sTfR level in the higher CRP level was not different from the normal CRP level. Feritin and sTfR level in the iron deficiency state was negatively correlated with moderate strength (r 0,676; rr=0,46) and 46% of subjects showed decreased feritin level associated with increased sTfR level. In the 47 pregnant women with iron deficiency; increased sTfR level was found in 19% of subjects and the ratio sTfR 1 log. feritin was found in 55% of subjects. The sTfR 1 log. feritin ratio was better than sTfR level in the detection of iron deficiency. We suggested to continue this research to prove that sTfR 1 log. feritin ratio more sensitive in the detection of iron deficiency, with the bone marrow iron stores as gold standard."

"PCSK9 berperan dalam regulasi homeostasis kolestrol dimana meningkatkan kadar LDL-C dengan mendegradasi reseptor LDL (LDL-R). Penelitian mengenai obat inhibitor PCSK9 masih dikembangkan namun metode uji in vivo yang memfasilitasi PCSK9 sangat terbatas terlebih di Indonesia. Maka dilakukan pembuatan model hewan tinggi PCSK9 menggunakan tikus tipe wild yang diinduksi diet tinggi fruktosa mengikuti penelitian yang telah dilakukan pada hamster dan mencit. Penelitian ini dilakukan pada tikus wistar jantan dengan menginduksi diet tinggi fruktosa (HFD) sebanyak 3mL/200grBB selama 3, 4, dan 5 minggu. Plasma dan jaringan ginjal diambil setiap durasi 3, 4 dan 5 minggu dan kadar PCSK9 diukur menggunakan uji ELISA. Sementara ekspresi PCSK9 ginjal dianalisis menggunakan metode western blot. Tikus kelompok HFD menunjukkan kadar PCSK9 plasma yang meningkat signifikan (p<0,05) terhadap kelompok kontrol durasi 3 dan 4 minggu. Durasi optimal peningkatan kadar PCSK9 plasma pada tikus adalah 4 minggu yang menghasilkan kadar PCSK9 sebesar 1389,02 ng/mL. Sementara kadar PCSK9 ginjal menurun signifikan (p<0,05) terhadap kelompok kontrol durasi 3 dan 4 minggu. Ekspresi mature PCSK9 ginjal kelompok HFD lebih tinggi dibandingkan kelompok kontrol.

PCSK9 plays a role in the regulation of cholesterol homeostasis which increases LDL-C levels by degrading LDL receptors (LDL-R). Research on PCSK9 inhibitor drugs is still being developed but in vivo test methods that facilitate PCSK9 are limited, especially in Indonesia. Therefore, an animal model for high PCSK9 was created using wild-type rats induced by a high-fructose diet following research that had been conducted on hamsters and mice. This research was conducted on male Wistar rats by inducing a high fructose diet (HFD) of 3mL/200grBW for 3, 4, and 5 weeks. Plasma and kidney tissue were collected every 3, 4 and 5 weeks and PCSK9 levels were measured using the ELISA test. While kidney PCSK9 expression was analyzed using western blot method. The HFD group rats showed significantly increased plasma PCSK9 levels (p<0.05) compared to the control group for 3 and 4 weeks duration. The optimal duration of increasing plasma PCSK9 levels in rats is 4 weeks which results in PCSK9 levels of 1389.02 ng/mL. Meanwhile, kidney PCSK9 levels decreased significantly (p<0.05) compared to the control group for 3 and 4 weeks duration. The expression of kidney mature PCSK9 in the HFD group was higher than the control group."

"Tikus merupakan salah satu binatang yang bisa menularkan penyakit. Berbagai  macam pengendalian tikus dilakukan oleh masyarakat. Salah satu cara pengendaliannya menggunakan kapur barus. Penelitian ini bertujuan untuk mengetahui efek kapur barus terhadap konsumsi pakan tikus Rattus norvegicus galur wistar. Jenis penelitian yang digunakan adalah penelitian quasi eksperimen dengan menggunakan kapur barus yang diletakkan berdekatan dengan tempat makan tikus yang kemudian dilihat rata-rata konsumsi pakan selama tiga hari. Hasil penelitian menunjukkan tidak ada perbedaan penggunaan kapur barus terhadap tikus. Hal ini dikarenakan kapur barus yang berupa padatan bersifat lebih sulit atau menguap pada area terbuka sehingga tidak terlalu menyengat indra  penciuman tikus.

Rats are animals that can transmit diseases. Various kinds of rat control are carried out by the community. One way to control it uses moth balls. This study aims to determine the effect of camphor on consumption of  Rattus norvegicus wistar strain rats feed. This type of research is a quasi experimental study using mothballs which are placed adjacent to a rat's place to eat and then see the average feed consumption for three days. The results of this study showed that there was no difference in the use of moth balls on rat. This is because moth balls in the form of solids are more difficult or evaporate in an open area so they do not overpower the rat's sense of smell."
