Curcumin is a natural yellow pigment isolated from the rhizomes of Curcuma longa L. (turmeric), and has several pharmacological effects and no toxicity in both in animal and human clinical study. However, the problem of curcumin is its stability because of its active methylene moiety. Modification of this moiety to cyclopentanone is expected to increase the stability. Previous study reported that benzylidenecyclopentanone analogues of curcumin showed inhibitory effect on histamine release from RBL-2H3 (rat basophilic leukemia) cells, a tumor analog of mast cells. One of them, the hydroxy-methoxy analog (PGV-0), showed more potent effect than that of curcumin. In the present study, some benzylidenecyclopentanone analogues of curcumin were evaluated for their effects on the viability and proliferation of RBL-2H3 cells. Viable cells were counted under a light microscope with a cells-counting chamber or using the cell viability reagent WST-1. The results showed that mast cell viability and histamine content were not affected by curcumin and benzylidene cyclopentanone for 30 min incubation, however, impaired for overnight incubation. The hydroxy-dimethyl benzylidene analog (PGV-1) strongly decreased the mast cells viability for overnight incubation, and its effect was highest among the other analogues. In the proliferation study, this compound also strongly inhibited the proliferation of mast cells, whereas curcumin and hydroxy-methoxy benzylidene analog inhibited the proliferation slightly. There were no inhibitory effects on mast cells proliferation treated by dibenzylidene; dihydroxybenzylidene; and hydroxy-diethylbenzylidene cyclopentanone.Keywords : viability, proliferation, curcumin, benzylidene cyclopentanone, RBL-2H3 cells

Tensigard is a phytofarmaca product of Agromed ( PT. Phapros Tbk., Semarang) formulated for antihypertension therapy. The product comprises celery extract (Apium graveolens) 75 % and kumis kucing extract (Orthosiphon stamineus Benth) 25 %. The aims of the research is to study whether Tensigard has an effect to decrease blood pressure in the normo and hypertensive (adrenaline induced hypertension) experimental animals. The specific aim of the study is to determine the D50 value of Tensigard to lower the blood pressure of the hypertensive experimental animals. The tests were conducted using anesthetized using anesthetized cats which were randomly divided into two groups, each of which consisted of 35 normotensive cats and the other 35 cats with hypertension (due to adrenaline treatment, in which the blood pressure was increased about 1,5 times than normal value). Furthemore, each group was devided into seven sub groups, each of which consists of 5 cats. One sub group was used as the control group, while the remaining sub groups were treated with Tensigard (6 dosage levels). The results of the studies indicated, that Tensigard has a hypotensive effect in the cats,either with normal or hypertension (adrenaline induced). The D50 value of the hypotensive effect in hypertensive cats is 16,37 ï± 1,08 mg/kg BW., in which the extrapolation of this dosage value for a 50 kg, human being is about 249,05 mg.Key Word : tensigard, antihypertension, effective dosage

Natrium pentagamavunonat-0 merupakan bentuk garam dari senyawa pentagamavunon (PGV-0). Modifikasi PGV-0 menjadi bentuk garam dimaksudkan untuk meningkatkan kelarutannya. Pada penelitian ini, natrium PGV-0 diuji pengaruhnya terhadap kontraksi otot polos aorta terisolasi yang diinduksi agonis reseptor a1 adrenergik, yaitu fenilefrin. Disamping itu, natrium PGV-0 juga dipelajari efek relaksasi pada organ tersebut. Hasil penelitian menunjukkan bahwa natrium PGV-0 menghambat kontraksi otot polos aorta tikus secara bermakna. Senyawa tersebut dapat menurunkan baik harga pD2 maupun efek maksimum dari fenilefrin. Disampimg itu, natrium PGV-0 menunjukkan efek relaksasi yang poten pada organ tersebut, dengan nilai pD2 sebesar 4,41. Berdasarkan hasil tersebut disimpulkan bahwa natrium PGV-0 menunjukkan efek yang poten pada otot polos aorta terisolasi yang diinduksi agonis reseptor a1 adrenergik. ABSTRACT PGV-0 is reported possessing some pharmacological effects such as anti-cancer, anti-allergy, anti-inflammatory, anti-oxidative etc. Its effects are more potent than curcumin. However, this compound has limitation in its solubility. Modifying the compound to its salt form is supposed to overcome this problem. The aim of the research is to investigate the effects of PGV-0 sodium on rat isolated-aortic smooth muscle contraction, and its relaxant effect on the tissue. The study was conducted using an isolated organ technique with an isotonic transducer. The percentage of response either contraction or relaxation was then plotted as a logaritmic scale of concentration-response curve to calculate pD2 value, a negative logaritmic of concentration of drug inducing 50% of maximum effect. The results have shown that treatment of PGV-0 sodium obviously inhibited the contraction of rat isolated-aortic smooth muscle induced by phenylephrine. The compound could decrease both pD2 and Emax values of phenylephrine significantly. The results indicate that PGV-0 sodium could attenuate both potency and intrinsic activity of contraction effect of phephylephrine. Besides, the compound also stimulated relaxant effects to a single phenylephrine contraction with pD2 value of 4.41. The compound could restore phenylephrine-induced tension into baseline level. Based on the results, PGV-0 sodium showed potent effects on rat isolated-aortic smooth muscle.

Proporsi pasien yang menggunakan statin ketika pertama kali masuk rumah sakit dengan stroke iskemik berulang sangat meningkat dengan cepat. Tetapi masih menjadi kontroversi. Hal tersebut yang melatarbelakangi penelitian ini dilakukan untuk mengetahui peranan terapi statin dengan luaran status fungsional pada pasien stroke iskemik berulang di rumah sakit Bethesda Yogyakarta. Penelitian ini adalah penelitian analisis dengan metode retrospective cohort menggunakan data data rekam medis pasien. Sebagai sampel dipilih kelompok pasien stroke iskemik berulang, baik yang mendapat pengobatan dengan statin ataupun yang tidak mendapatkan pengobatan statin. Kemudian secara retrospektif diamati pengaruh penggunaan statin terhadap luaran status fungsional pasien. Jumlah subyek untuk masing masing kelompok adalah 77 pasien. Luaran baik ditandai dengan nilai mRS 0-3, sedangkan luaran buruk ditandai dengan 4-6. Lokasi penelitian adalah di rumah sakit Bethesda Yogyakarta. Penggunaan statin pada pasien stroke iskemik berulang dapat memberikan luaran status fungsional yang baik di RS Bethesda Yogyakarta (p = 0,022; RR=1,56; IK 95% = 1,056 – 2,305). Selain itu penelitian ini juga memberikan luaran sekunder yaitu variabel usia, GCS, dan kelemahan otot gerak memiliki hubungan bermakna terhadap luaran status fungsional pasien stroke iskemik berulang. Faktor prediktor untuk mendapatkan luaran status fungsional yang baik pada penelitian ini adalah pasien tanpa penggunaan antibiotik, GCS 13-15, penggunaan anti koagulan, pasien tanpa analgetik antipiretik, dan pasien dengan penggunaan anti platelet.Penggunaan statin pada pasien stroke iskemik berulang dapat memberikan luaran status fungsional yang baik di RS Bethesda Yogyakarta
