Ideal gel formulation can be obtained by formulating some kind of gelling material, but the most important thing to note is the selection of a gelling agent. HPMC (Hidroxy Propyl ABSTRAKSediaan gel yang baik dapat diperoleh dengan cara memformulasikan beberapa jenis bahan pembentuk gel, namun yang paling penting untuk diperhatikan adalah pemilihan gelling agent. HPMC (Hidroxy Propyl Methyl Cellulose) merupakan gelling agent yang sering digunakan dalam produksi kosmetik dan obat, karena dapat menghasilkan gel yang bening, mudah larut dalam air, dan mempunyai ketoksikan yang rendah. Penelitian ini bertujuan untuk memperoleh konsentrasi HPMC sebagai gelling agent yang memiliki kestabilan fisika yang sesuai dengan persyaratan yang telah ditetapkan. Formulasi gel dibuat dengan variasi konsentrasi HPMC 3%, 5% dan 7%, selanjutnya dilakukan evaluasi sifat fisika yang meliputi uji organoleptis, homogenitas, daya sebar, pH, dan viskositas. Evaluasi basis gel dilakukan selama 3 minggu. Hasil yang diperoleh dari uji stabilitas menunjukan basis gel dengan konsentrasi HPMC 7% memiliki standar yang baik untuk viskositas, pH, daya sebar, homogenitas dan organoleptis.

Clostridium meningitis is a rare complication of elective surgery, but the presence of pneumocephalus on CT in the absence of penetrating injuries, should raise the possibility of anaerobic infections. We report a case of fatal Clostridium perfringens meningitis which occurred 4 months after a craniotomy for glioblastoma multiforme. The diagnosis was suspected based on the CT findings. The literature of this rare condition is reviewed.

In the field of neurosurgery, often the dura mater cannot be sutured, and consequently, it requires a duraplasty procedure using a dural fascial graft. Since 1890, various materials have been researched as dura mater substitutes. Amniotic membrane, for example, is suitable as a dural graft material and has been used in neurosurgery since 2012. However, there has been little research on human patient's dural healing after the use of amniotic membrane in their duraplasty procedure. To address this gap, a clinical experimental study was undertaken to evaluate the human dural healing of 16 patients who had undergone duraplasty in decompressive craniectomy surgery at Dr. Soetomo General Hospital, Surabaya. The amniotic membrane allograft, was sutured to cover the dural defect for eight randomly chosen patients (Group I). The fascial autograft from the temporal muscle had been applied for eight other patients (Group II). Between 10 and 20 weeks after surgery, the patients underwent cranioplasty and dural healing evaluation by cerebrospinal fluid (CSF) leakage testing through the edge of the dural defect. The fibrocyte infiltration around the edge of the dural defect was examined histologically. Statistical analysis, using an independent t-test, was performed with a confidence interval of 95%. The results of the clinical and histological analysis suggest that an amniotic membrane graft was able to provide watertight dural closure and adequate fibrocyte infiltration comparable with that provided by temporalis muscle fascia. This study shows that using an amniotic membrane in neurosurgery has a potential advantage over an alternative dural healing.

ABSTRAKPenelitian bioaktivitas ekstrak methanol dan farksi n-heksana daun sungkai (Peronema canesens JACK) dengan metode brine shrimp lethality test (BSLT) telah dilakukan pengujiannya. Penelitian ini bertujuan untuk mengetahui rendemen ekstrak, dan bagaimana bioaktivitasnya terhadap Artemia salina Leach. Penelitian ini menggunakan metode brine shrimp lethality test dimana data penelitiannya diperoleh dengan mengamati jumlah hewan uji yang mati, kemudian data tersebut diolah dengan menggunakan tabel Reed and Muench. Hasil pengujian ekstrak daun sungkai dengan metode brine shrimp lethality test bersifat bioaktif terhadap larva Artemia salina Leach. Dengan nilai LC 50 . dari ekstrak methanol adalah 387,257 ppm dan n-heksana adalah 107,399 ppm.
