Family planning is a program designed to control the rate of population growth extensively in the country of Indonesia. In order to avoid of potential destructive effects of population explosion, a nation-wide Family Planning Program has been adopted long-standing in Indonesia. As to make it successful, family planning would have to involve with participation of both males and females. It was aimed to prove that the ethanol extracts of a local plant, Bali papaya, have antifertility function via inhibiting the secretion of FSH and LH. Randomized post-test only control group design was selected for this study. 38 male mice (strain Balb-C) were used and randomly divided into two equal groups. Only 0.5 ml double-distilled water was applicated orally for 36 days to controls; and 0.5 ml ethanol extract of unripe papaya seed with dose of 20 mg/20gr BW/day for 36 days to treatments. At the end of the experimental duration, blood samples of each individuals of both of the groups were collected for FSH and LH measurement. FSH and LH levels in controls were recorded as 3.379 and 15.718 mIU/ml, respectively. In experimental animals, the level of FSH was declined to 2.053 mIU/ml, while LH was measured as 8.626 mIU/ml. The reduction of both of the hormone was probably related to the active substances of extract. Administration of the ethanol extract of papaya seed reduces the average level of FSH and LH (p<0.05), significantly.

This study was to evaluate the effects of supplementation of ethanol extracts of chive (CE) and ginger (GE), and their combination (CG) in diets of broiler chickens on their growth, health performance and economic efficiency. Totally 180 male Egyptian broilers from one-day age were randomly assigned to 6 dietary treatments consisting of 3 replicates of 10 chicks each, of which in the diet of the control group (CT) neither ginger nor chive preparation were introduced, meanwhile the diets of birds in the 5 trial groups (CE1, CE2, GE1, GE2 and CG) were supplemented with 0.5% CE, 1% CE, 0.5% GE, 1% GE and 0.5% CE plus 0.5% GE preparations, respectively. In general, supplementation of CE and GE did not significantly affect feed consumption, mortality, performance efficiency index (PEI), and respiratory syndrome in chickens. However, the herb extract preparations could reduce the incidence of diarrhea in broiler chickens during five to-ten-week age periods. Microscopic examination of small intestinal mucosa showed that the heights of villi and the depths of crypts of chicks in the CE2 treatment as well as the diameters of villi of chicks in the CG treatment were significantly (p < 0.05) higher than in the others. In general, supplementation of 1% CE and the combination of 0.5% CE and 0.5% GE preparations improved the growth performance of broilers, and the combination can be an alternative to antibiotics as growth promoters in feeding chicken.

The survey results in Indonesia in 2017 showed that the diarrhea morbidity rate for all age groups was 6.897.463. In Indonesia, unripe wooden banana has been used empirically as an antidiarrheal by the people in Senduro village, Lumajang, East Java. The study aimed to prove the antidiarrheal effect of ethanol extract of unripe wooden banana (Musa paradisiaca L.) in male Balb-C/mice induced by Escherichia coli bacteria. This study was a laboratory experimental study with post-test only control group design that used 40 mice divided into 8 groups, namely 1 group without treatment (normal mice) and 7 groups induced by Escherichia coli (1 negative control group given CMC-Na, 3 groups positive controls were given Loperamid HCL 0,5 mg/kgBW, 1 mg/kgBW and 2 mg/kgBW and 3 treatment groups were given extracts 100 mg/kgBW, 200 mg/kgBW and 400 mg/kgBW). Observation of animals in this study was carried out for 4 hours. Data were analyzed of frequency of diarrhea, fecal weight and fecal consistency used Kruskal Wallis and the results showed significant differences between treatment groups (p <0.05). From the results of the Mann-Whitney test, the ethanol extract of unripe wooden banana with a dose of 100 mg/kgBW was not significantly different (p> 0.05) with the control group of Loperamid HCL dose of 0.5 mg/kgBW. Unripe wooden banana had been shown to have antidiarrheal activity at an extract dose of 100 mg/kg BW in terms of the parameters of fecal consistency, frequency of diarrhea, and fecal weight. The results showed that the higher the dose, the better antidiarrheal activity.

Many human anatomy courses are taught using cat dissection. Alternatives are available, but information regarding learning outcomes is incomplete. In 2003, ∼120 undergraduates enrolled in a human anatomy course were assigned to one of two treatment groups. In the control group, students performed cat dissections (emphasizing isolation and identification) of the muscular, digestive, and cardiovascular systems. In the experimental treatment group, students built clay sculptures of each human body system. Student learning was evaluated by using both low- and high-difficulty questions. On pre- and postexperiment control exams, there were no significant differences in student performance. On exams after a cat dissection vs. a human-clay sculpting experience, the students in the human-clay sculpting treatment group scored significantly higher than their classmates in the cat dissection group on both the low- and high-difficulty questions. Student attitudes toward dissection and taking future human anatomy courses were also measured. There were no differences in student attitudes at the beginning of the experiment; afterward, students exposed to a cat dissection experience viewed dissection more favorably than students in the human-clay sculpting treatment group. There were no treatment effects on student willingness to take future human anatomy courses. The experimental design makes it difficult to conclude precisely why students assigned to the human-clay sculpting experience performed better on exams, but as each method was performed in this particular human anatomy course, our data indicate that human-clay sculpting may be a viable alternative to cat dissection in an anatomy course in which the students focus on human anatomy.

Pangdahai is a traditional Chinese drug, specifically described in the Chinese Pharmacopoeia as the seeds ofSterculia lychnophoraHance. Here, we separatedS. lychnophorahusk and kernel, analyzed the nutrient contents, and investigated the inhibitory effects ofS. lychnophoraethanol extracts on cariogenic properties ofStreptococcus mutans, important bacteria in dental caries and plaque formation. Ethanol extracts ofS. lychnophorashowed dose-dependent antibacterial activity againstS. mutanswith significant inhibition at concentrations higher than 0.01 mg/mL compared with the control group (p<0.05). Furthermore, biofilm formation was decreased byS. lychnophoraat concentrations > 0.03 mg/mL, while bacterial viability was decreased dose-dependently at high concentrations (0.04, 0.08, 0.16, and 0.32 mg/mL). Preliminary phytochemical analysis of the ethanol extract revealed a strong presence of alkaloid, phenolics, glycosides, and peptides while the presence of steroids, terpenoids, flavonoids, and organic acids was low. TheS. lychnophorahusk had higher moisture and ash content than the kernel, while the protein and fat content of the husk were lower (p<0.05) than those of the kernel. These results indicate thatS. lychnophoramay have antibacterial effects againstS. mutans, which are likely related to the alkaloid, phenolics, glycosides, and peptides, the major components ofS. lychnophora.

Gentamicin can induce damage to the kidney because of the accumulation of epithelial cells in the cortex. This accumulation can cause an increase in Reactive Oxygen Species (ROS), which in turn can trigger an increase in free radicals which causes a decrease in kidney function, which can be seen with Blood Urea Nitrogen (BUN) and sCr (serum creatinine) parameters. Garlic (Allium sativum L.) contains several bioactive compounds, including alliin, allisin, ajoene, and allil cysteine. The content of allisin has activity as an antioxidant. This study used a nephrotoxic mouse modelling method with 100 mg/kgBW of gentamicin induction intraperitoneally, then BUN and sCr levels were checked 24 hours after the 10th day induction. This study aimed to determine the effect of garlic ethanol extract in preventing the decline of renal function in rats induced by gentamicin with a parameter of BUN and sCr. The animal test were divided into 5 treatment groups, normal control group, negative controls, and three treatment groups at a dose of 50, 120, and 300 mg/kgBW for 10 days of concurrent treatment between extracts with gentamicin. The results of the study showed that garlic ethanol extract with a dose of  50, 120, 300 mg/kgBW was able to prevent a decrease  in kidney function due to the administration of gentamicin significantly when compared with negative controls (p 0,05).

Antidiabetic activity of Vernonia amygdalina and its possible synergism with glibenclamide was checked. Forty eight rats were used for the research, for hypoglycermic study of V. amygdalina alone, they were grouped into five of six rats each. Group 1 was the negative control and was administered distilled water orally. Groups 2, 3, and 4 were the treatment groups which received 100, 200 and 300 mg/kg body weight of the V. amygdalina extract respectively orally by intubation. Group 5 was the positive control group which received a known antidiabetic drug, glibenclamide. Diabetes was induced with alloxan. For the synergism study, another 18 rats grouped into 3 of six rats each was used. Both groups of glibenclamide only and glibenclamide plus V. amygdalina extract were dosed for 14 days orally by intubation, thereafter were sacrificed and blood collected from heart for analysis. There were 5 replicates grouped by weight throughout the study and both single and synergistic studies had the same controls. Effect of V. amygdalina extract was checked on blood glucose and its possible synergism with glibenclamide. All results in treatment groups were compared with the normal control at statistical confidence of p<0.05. Result shows that V. amygdalina extract reduced blood glucose level in the test groups as dose of extract increased. Combination of V. amygdalina with glibenclamide demonstrated further deduction in blood glucose levels in the treatment rats groups. Therefore addition of V. amygdalina into glibenclamide increased efficacy in the diabetic rats. The interaction between V. amygdalina and glibenclamide in this work was additive and therefore synergistic.
