If one believes the hype it sounds like a veritable fountain of youth.] Zhongguo Zhong Xi Yi Jie He Za Zhi. 1993 Jun;13(6):349-51, 325-6. [Effect of wuzi yanzong liquid on hypothalamus, monoamines, sexual hormones and reproductivity in male rats] About 100 male SD rats aged 2, 5, 10, 18 and 24 months (each age group for about 20 rats) were used in the anti-senility experiment. The animals of each age group were further subdivided into two groups randomly: one group administered with Wuzi Yanzong Liquid (WYL) daily for 5 weeks, and the other group with normal saline. After treatment, plasma testosterone (T) and estradiol (E2), hypothalamus norepinephrine (NE), dopamine (DA) and serotonin (5-HT) levels were determined. In comparison with younger groups, the 18 and 24 months old rats administered with saline had markedly lowered plasma T, hypothalamus NE and DA levels, and elevated 5-HT, E2 levels and 5-HT/DA, E2/T ratios; while in the 18 and 24 months rats administered with WYL the above mentioned changes were much less remarkable. Since WYL only raised plasma T level in old rats but not in younger ones, this drug seems to have different action from testosterone preparations. In another animal experiment, the reproduction promoting effect of WYL was shown by the increase of sperm count and motility of sperms in old male rats as well as its reproductive ability.

[Clinical study on treatment of mild cognitive impairment by modified wuzi yanzong granule] OBJECTIVE: To observe the clinical efficacy and safety of modified Wuzi Yanzong Granule (MWYG) in treating mild cognitive impairment (MCI), and to explore its mechanism. METHODS: Forty-four MCI patients were selected referring to the international recognized Peterson's criteria and randomly divided into two groups, the treated group treated with MWYG and the control group treated with Ginkgo leaf extraction, with the course of 3 months for both groups. Changes of memorial quotient (MQ), superoxide dismutase (SOD) activity, malondialdehyde (MDA) content, mitochondrial DNA (mtDNA) deletion rate and acetylcholinesterase (AchE) before and after treatment were observed. RESULTS: After treatment, levels of MQ, serum SOD activity increased and serum MDA content, mtDNA deletion rate and AchE decreased in both groups (P < 0.01), but the difference between the two groups was insignificant. No adverse reaction was found in two groups. CONCLUSION: Both MWYG and Ginkgo leaf capsule can effectively improve the memorial function of patients with MCI, the therapeutic mechanism is possibly related with the actions in reducing AchE activity, improving free radical metabolism, and alleviating mitochondrial DNA oxidation damage.

[A clinical study of the effect of wuzi yanzong solution in retarding aging process] Eighty men ranging from 60 to 80 years old were selected, in whom no disease was found through a thorough check-up except for some senility manifestation diagnosed as deficiency of the kidney. They were randomly divided into two groups, wuzi yanzong solution (WYS) being administered in 50 cases and placebo in 30. After 5 weeks' treatment, symptoms such as hypomnsis, tinnitus, and aching of the back and legs, dribbling after urinary voiding, and nocturia were remarkably improved in the WYS group, but they remained as before in the placebo group. Before the treatment, plasma lipid peroxide (LPO), erythrocyte superoxide dismutase (SOD), blood glutathione peroxidase (GSH-Px), serum luteinizing hormone (LH) and follicle-stimulating hormone (FSH), plasma testosterone (T) and estradiol (E2) levels were determined. In comparison with the results obtained in 33 young men in their twenties, LPO, FSH, LH level and E2/T ratio in the aged were greatly elevated, and SOD, GSH-Px and T markedly lowered. After the treatment, there was remarkable reduction of LPO and E2/T, and increase of SOD and T in the WYS group, but no significant change in the placebo group. The above results not only indicate the beneficial effect of WYS in retarding the aging process, but also suggest the possible mechanism of reducing the peroxidation of fatty acids by enhancing the antioxidant enzymes to inhibit free radical activity.

[Leukogenic effect and antioxygen radicals function of fufang wuzi yanzong pills] Fufang wuzi yanzong pills have strong leukogenic effect on cyclophosphamide induced leukopenia in mice. It can decrease the lipid peroxide (MDA) content of liver in rats and lipofuscin contents of heart and kidney in mice and increase the superoxide dismutase (SOD) activity of liver in rats.

[Effect of wuzi yanzong Pill on mitochondrial DNA deletion and respiratory chain enzyme complex activity in peripheral leukocyte of aged male with kidney deficiency syndrome] OBJECTIVE: To investigate the effect of Wuzi Yanzong Pill (WZYZP) on mitochondrial DNA (mtDNA) deletion and respiratory chain enzyme complex (RCZC) in peripheral blood leukocyte of aged male with Kidney Deficiency Syndrome (KDS). METHODS: Single-blinded study was conducted in 38 aged male with KDS, who were randomly divided into 2 groups treated with WZYZP and placebo respectively for 3 months. Levels of mtDNA deletion and RCZC were determined by polymerase chain reaction (PCR) and enzyme kinetics technique respectively. RESULTS: WZYZP could reduce the mtDNA deletion and raise the activity of mitochondrial RCZC I, IV in peripheral blood leukocyte of aged male with KDS (P < 0.05, P < 0.01). CONCLUSION: WZYZP has protective effect on mtDNA from oxidative damage in leukocyte of aged male with KDS.

METHODS: Animal experiments with polymerase chain reaction (PCR), enzyme kinetics and bioluminescence technique were conducted. RESULTS: WZYZP and its disassembled prescription of Fructus Lycii and Semen Cuscutae could reduce the mitochondrial DNA deletions and raise the activities of mitochondrial respiratory chain complexes I, IV and adenosine triphosphate (ATP) synthesis in aged rats' brain; Fructus Lycii and Semen Cuscutae could also reduce the mitochondrial DNA deletions in aged rats' heart (P < 0.05, P < 0.01). CONCLUSION: WZYZP, Fructus Lycii and Semen Cuscutae have protective effect on oxidative damage of mitochondrial DNA in aged rats. J Ethnopharmacol. 2002 Oct;82(2-3):169-75. Protective effect of Fructus Lycii polysaccharides against time and hyperthermia-induced damage in cultured seminiferous epithelium. Lycium barbarum L. (Solanaceae) is a Chinese medicinal plant whose fruits (Fructus Lycii) are used by Chinese physicians for treatment of infertility. However, the active ingredients and the mechanism of action underlying Lycium's fertility-facilitating effects remain unknown. Here we report that Fructus Lycii polysaccharides (FLPS) inhibit time- and hyperthermia-induced structural damage in murine seminiferous epithelium, in vitro. Moreover, we found that FLPS delayed apoptosis in this system, both at normothermic and hyperthermic culture conditions. Oxidative stress was reported to be a major cause of structural degradation and apoptosis in hyperthermic testes, and thus the protective effect of FLPS could implicate an antioxidant mechanism of action. To test this hypothesis we assayed the effect of FLPS on ultraviolet light-induced lipid peroxidation, and cytochrome c reduction by free radicals. We found that FLPS is a potent inhibitor of both of these reactions. Together, these results demonstrate the protective effect of FLPS on time- and hyperthermia-induced testicular degeneration in vitro, indicate the potential mechanism of action for this protective effect, and provide a scientific basis for the traditional use of this plant. [Wuzi yanzong contains fructus lycii.] Biomed Environ Sci. 1996 Mar;9(1):67-70 The inhibitory effect of extracts from Fructus lycii and Rhizoma polygonati on in vitro DNA breakage by alternariol. Alternariol caused DNA single-strand breakage. Conversion of the closed circular double-stranded supercoiled DNA (pBR 322) to the nicked circular form and linear form was used to investigate the effect of extracts of some Chinese medical herbs on DNA nicking induced by alternariol. Some substances in the extracts of Rhizoma polygonati (RP) and Fructus lycii (FL) were shown to protect DNA from the attack by alternariol. Some substance in the RP may bind to plasmid DNA, and this binding reduces the electrophoretic mobility of DNA. These results indicate that substances from FL and RP may be used as DNA protectors. It is possible that they play an important role in preventing cancer. Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=27391
