: This study aimed to obtain the effect of pumpkin fruit pulp (Cucurbita moschata D.) juice on total blood cholesterol of wistar rats (Rattus norvegicus). This was an experimental laboratory study conducted in the Laboratory of Pharmacology and Therapy Faculty of Medicine, University of Sam Ratulangi. Samples were 10 rats with an average body weight of 150 g. Samples were divided into 5 groups, each group consisted of 2 rats: negative control group, only used standard food; propylthiouracil (PTU) treatment group; positive control group used simvastatin after PTU induced for 14 days; propylthiouracil (PTU) treatment group continued with standard food; and propylthiouracil (PTU) treatment group continued with pumpkin fruit pulp juice. Doses of the pumpkin fruit pulp juice were 0.93 g/ml/day/rat as many as 2 ml/day. The measurement of total blood cholesterol levels was on days 0, 15, and 22 by using Autocheck.

Uji Daya Hambat Ekstrak Biji Pala (Myristicae Fragrans)terhadap Pertumbuhan Bakteri Staphylococcus Aureus Dan Streptococcus Pyogenes

: People of Indonesia especially in North Sulawesi often use nutmeg powder for wound treatment. Comensalist bacterias that live in human skin, like Staphylococcus aureus and Streptococcus pyogenescan infect open wound especially those that are not treatedwell. This study aimed to find out the result of nutmeg extract inhibition test on Staphylococcus aureus and Streptococcus pyogenes. This was a laboratory experimental study using modified Kirby-Bauer wells at Phytochemistry and Micobriology Laboratory of Sam Ratulangi University Faculty of Mathematics and Science. Nutmeg extract was obtained from maceration process with 96% ethanol. Concentrations of the thick extract that was used were 100 mg/ml, 50 mg/ml, 25 mg/ml, and 12,5 mg/ml. Cefuroxime was used as positive control and aquades was used as negative control. The results showed that aquades had no inhibition zone. Cefuroxime had the widest diameter of inhibition zone. The average of inhibition diameter that was produced by Cefuroxime was 37,33 mm toward S. Aureus bacteria and 42,67 mm toward S. Pyogenes bacteria. Nutmeg extract with 100 mg/ml concentration produced a 25,16 mm inhibition zone diameter on S. Aureus bacteria and 24,16 mm on S. Pyogenes bacteria. Nutmeg extract with 25 mg/ml concentration produced a 19,16 mm diameter on S. Aureus bacteria and 20,66 mm on S. Pyogenes bacteria. While nutmeg extract with 12,5 mg/ml concentration prodyced a 16,16 mm diameter on S. Aureus bacteria and 18,16 mm on S. Pyogenes bacteria. Conclusion: Nutmeg extract has a potential inhibition effect on the growth of S. Aureus and S. Pyogenes bacteria. The inhibition effect of nutmeg extract is stronger on S. Pyogenes than S. Aureus

These bacteria represent negative Gram bacteria and positive gram bacteria. The study aimed to determine antibacterial effect of Cinamon bark againts E.coli and S.pyogenes by measuring the diameters of the inhibition zones. Cinamon bark samples were taken from Kaneyan, South Minahasa, and then be extracted by maceration using 80% etanol. The results showed that the total diameter of the inhibitory zone of Cinamon bark extract against E.coli was 43 mm with an average of 14,3 mm, and the total diameter of the inhibitory zone against S.pyogenes was 75 mm with an average of 25 mm. Conclusion: Cinamon bark extract had antibacterial effect against E Escherichia coli and Streptococcus pyogenes
