The Brain is an organ that is vulnerable to hypoxia. Hypoxia induces neuronal cell death especially in cerebral cortex neuron. Until now, there are no neuroprotective agents that are recommended for ischemic stroke. Among all potential therapies, Acalypha indica (AI) and Centella asiatica (CA), are examples of promising herbs for preventing cell damage from hypoxia through their antioxidant activity. The research purpose was to show the neuroprotective capabilities of these herbs by examining their histopathological features. Thirty hypoxia-induced male Spraque-Dawley rats were given treatment that contain the combination of AI and CA (AI 200 mg/kgBW + CA 150 mg/kgBW and AI 250 mg/kgBW + CA 100 mg/kgBW) and a single CA 100 mg/kgBW. Through the histopathological examination, percentages of the normal cells were counted and analyzed. One way ANOVA was conducted and the results did not show a statistically significant difference between all of the groups (p=0.575). The quantitative results depict an increase in the percentage of normal neuron cells in all of the exposed groups compared to the negative control group: combination 2 (15,43%), combination 1 (11,46%) and single CA (3,3%), respectively. Thus, the combination of AI and CA treatment have a trend toward restoring the neuron damage."

"The aim of this book is to provide insight into the principles of operation of the cerebral cortex. These principles are key to understanding how we, as humans, function. There have been few previous attempts to set out some of the important principles of operation of the cortex, and this book is pioneering. The book goes beyond separate connectional neuroanatomical, neurophysiological, neuroimaging, neuropsychiatric, and computational neuroscience approaches, by combining evidence from all these areas to formulate hypotheses about how and what the cerebral cortex computes. As clear hypotheses are needed in this most important area of 21st century science, how our brains work, I have formulated a set of hypotheses about the principles of cortical operation to guide thinking and future research. The book focusses on the principles of operation of the cerebral cortex, because at this time it is possible to propose and describe many principles, and many are likely to stand the test of time, and provide a foundation for further developments, even if some need to be changed. In this context, I have not attempted to produce an overall theory of operation of the cerebral cortex, because at this stage of our understanding, such a theory would be incorrect or incomplete. However, many of the principles described will provide the foundations for more complete theories of the operation of the cerebral cortex. This book is intended to provide a foundation for future understanding, and it is hoped that future work will develop and add to these principles of operation of the cerebral cortex. The book includes Appendices on the operation of many of the neuronal networks described in the book, together with simulation software written in Matlab."

"Stroke adalah suatu penyakit serebrovaskular yang disebabkan oleh berhentinya aliran darah arteri ke otak. Sekitar 80-85% stroke adalah stroke iskemik yang disebabkan oleh obstruksi pada arteri di sirkulasi serebelum. Hipoksia serebral yang terjadi akibat iskemik pada otak tersebut menimbulkan perubahan pada morfologi sel dan kemudian kematian sel dimana sel neuron menjadi piknotik bermanifestasi berupa kecacatan neurologis pada penderitanya, sehingga penderita stroke harus mengonsumsi obat jangka panjang untuk kesembuhannya. Citicoline merupakan obat yang efektif untuk stroke dari penelitiannya namun memiliki kelemahan dari segi pemakaian dan harga yang mahal menyebabkan obat ini kurang efisien di masyarakat. Tanaman herbal akar kucing dan pegagan merupakan obat alternatif pada terapi stroke karena efek neuroprotektifnya. Dosis kombinasi kedua herbal ini diharapkan mampu memberikan perubahan jumlah pada sel piknotik di otak. Penelitian ini bersifat eksperimental dengan melakukan percobaan pemberian ekstrak akar kucing dan pegagan terhadap tikus terhadap 5 kelompok tikus yang dibuat hipoksia dengan berbagai jenis perlakuan yaitu pemberian akuades, citicolin, dosis akar kucing 150,200,250mg dikombinasikan dengan pegagan 150mg. Serebelum tikus kemudian diambil dan dibuat sediaan preparat histopatologi untuk dilihat perubahan terhadap sel piknotik di girus dentatus internus. Dari hasil uji One away Anova didapatkan bahwa tidak terdapat perubahan jumlah sel piknotik yang bermakna terhadap perlakuan yang diberikan terhadap tikus (p> 0,05). Pada penelitian ini dapat disimpulkan bahwa terapi kombinasi kedua herbal tersebut tidak memberikan perubahan jumlah sel piknotik pada girus dentatus internus tikus.

Stroke is cerebrovascular disease caused by cessation of arterial blood flow to the brain. Approximately 80-85% of strokes are ischemic strokes caused by arterial obstruction in the circulation of cerebellum. Cerebral hypoxia caused by ischemia of the brain gives result in alteration of cells morphology and cell death in which neuron cells become picnotics. This will later manifests in the form of neurological disability shown in the affected individuals resulting in the need to take long term medication. Citicoline is an effective drug for stroke based on research but has drawbacks in term of usage and high price which cause it to be less efficient in the community. The herbs cat root and Indian pennywort are alternative drugs for stroke therapy because of its neuroprotective effects. Combination dose of these two herbs are expected to provide a change in number of picnotic cells in rat?s brain.

This research experiments on giving the extract of cat root and indian pennywort to 5 groups of hypoxic rats in various dose (150, 200, 250 mg of cat root combined with 150 mg of Indian pennyworts), negative control is given aquades and positive control is given citicoline. The cerebellum of the rats is then taken and is made to histopathologic preparation to see the changes of picnotic cells in gyrus dentatus internus.

From the One Way Anova test results, it can be seen that there is no meaningful changes in the number of picnotic cells after the treatments are given to the rats (p>0,05). In conclusion, therapy with combination of cat root and Indian pennywort does not provide changes in number of picnotic cells in gyrus dentatus internus of the rats. "
