ABSTRACT
Erectile dysfunction (ED) is a highly prevalent disorder that affects millions of men worldwide. ED is now considered an early manifestation of atherosclerosis, and consequently, a precursor of systemic vascular disease. This study was designed to investigate the effects of male silkworm pupa powder (SWP) on the levels of nitric oxide synthase (NOS) expression, nitrite, and glutathione (GSH); lipid peroxidation; libido; and erectile response of the corpus cavernosum of the rat penis. We induced ED in the study animals by oral administration of 20% ethanol over 8 weeks. The SWP-treated male rats were divided into 3 groups that were orally administered 200, 400, and 800 mg/kg. The libido of the SWP-administered male rats was higher than that of the ethanol control group. In addition, the erectile response of the corpus cavernosum was restored in males on SWP administration, to a level similar to that of the normal group without ED. The testosterone concentration did not increase significantly. The lipid peroxidation in the corpus cavernosum of the male rats administered SWP decreased significantly. In contrast, compared to the ethanol group, SWP-administered male rats showed increased GSH levels in the corpus cavernosum. The level of nitrite and NOS expression in the corpus cavernosum of SWP-administered male rats increased significantly. These results indicated that SWP effectively restored ethanol-induced ED in male rats.

Constipation is one of the most common functional digestive complaints worldwide. We investigated the laxative effects of figs (Ficus carica L) in a beagle model of constipation induced by high protein diet and movement restriction. The experiments were consecutively conducted over 9 weeks divided into 3 periods of 3 weeks each. All 15 beagles were subjected to a non-treatment (control) period, a constipation induction period, and a fig paste treatment period. We administered fig paste (12 g/kg daily, by gavage) for 3 weeks following a 3-week period of constipation induction in dogs. Segmental colonic transit time (CTT) was measured by counting radiopaque markers (Kolomark) using a radiograph performed every 6 h after feeding Kolomark capsules, until capsules were no longer observed. Fig paste significantly increased fecal quantity in constipated dogs, and segmental CTT was also reduced following fig paste administration. There were no significant differences in feed intake, water intake, body weight, or blood test results, between the constipation and fig paste administration periods. Our results demonstrate that fig is an effective treatment for constipation in beagles. Specifically, stool weight increased and segmental CTT decreased. Fig pastes may be useful as a complementary medicine in humans suffering from chronic constipation.

Scute/larisa baica/ensis (SB) has been used as a folk medicine for curing ulcer, inflammation and infection. However, surprisingly little has been done to develop and exploit SB's immunomodulating, anti- inflammatory properties. Moreover, the mechanisms of SB-action on immune function had not been elucidated. The present study was undertaken to investigate the effect of 5B on immune functions, microbial growth and bacterial mutagenicity. Boiling water extract of SB was used in this experiment. The proliferation response to PHA-, Con A- or LPS-stimulation and the production of Con A-induced IL-2 and LPS-induced IL-6 of splenocytes from SB-pretreated mice were significantly higher than those of splenocytes from control mice. Daily single injection of 2 mg/mouse SB for 4 days resulted in enhancement of Arthus reaction and DTH to SRBC. And these enhancements were more prominent when SB was treated prior to SRBC- sensitization. SB did inhibit the growth of microorganisms such as C. albicans, C. neoformans, E. coli S. typhimurium and this inhibiting effect was gradually increased in proportion to the increment of SB. SB also remarkably reduced the mutagenicity of mutagens such as sodium azid and benzo[a]pyrene, but this was not certain, because it showed a killing effect on the cell survival test. When SB treated mice were i.p infected with C. albicans, the number of microorganisms in the peritoneal exudates were significantly reduced. Taken together, these results revealed that SB itself has not only multiple effects on events controlling immune responses but also anti-inflammatory properties, which may provide the rational basis for their therapeutic use as one of the biological response modifiers.
