Antifungal effects of the extract of the Withania somnifera on Candida albicans

Abstract: Background and aims: Withania somnifera (W. somnifera), commonly known as Ashwagandha, is an important medicinal plant that has been used in Ayurvedic and indigenous medicine for over 3,000 years. Candidiasis is one of the most common opportunistic fungal diseases in humans. In fact, the most important fungal disease in women is vaginal candidiasis. This study aimed to investigate the antifungal effects of the extracts of the W. somnifera on Candida albicans (C. albicans). Methods: In this experimental research, 9 vaginal samples were collected using the sterile swap and Falcon tube by the gynecological specialists. The extracts of the shallot and artichoke were prepared using a rotary device. The inhibitory concentration against C. albicans was determined using incubation in media. Results: The results of this study suggested that the minimum inhibitory concentration (MIC) against C. albicans, which is equivalent 50 ppm to 250 ppm has the highest concentration of inhibitor. Conclusion: The results of this study showed that the antifungal activity of wind cheese against C. albicans is good, so it can be used as a drug to treat infections caused by C. albicans.

In vivo, effect of herb (Withania somnifera) on immunomodulatory and antioxidative potential of milk in mice

Abstract: Eighteen healthy male Swiss albino mice of specific weight (25–30g) were randomly divided into three groups of six animals each and given specific diets for a period 28 days. Group A was given normal synthetic diet (NSD) and milk; Group B: NSD and Withania somnifera (WS) extract (0.3%) and Group C: NSD supplemented with milk and WS extract (0.3%). The phagocytic activity of peritoneal macrophages and Immunoglobulin G (lgG) level in mice serum increased significantly in comparison to control group in WS-supplemented groups. The lymphocyte proliferation index did not alter significantly (P < 0.05) in supplemented groups after a period of 28 days. Group B and C showed significantly higher reduced glutathione level and significantly lowered (P < 0.05), carbonyl protein and thiobarbituric acid reactive substances in liver and red blood cells lysates as compared to control. This finding indicated that aqueous extract of WS is able to enhance immunomodulatory and antioxidative properties of milk.

Therapeutic effects of hydro-alcoholic leaf extract of Withania somnifera on age-induced changes in daily rhythms of Sirt1, Nrf2 and Rev-erbα in the SCN of male Wistar rats.

Abstract: The temporal expression pattern of the circadian clock genes are known to be altered/attenuated with advance in age. Withania somnifera (WS) essentially consists of numerous active constituents including withanolides is known to have antioxidant, anti-inflammatory and adaptogenic properties. We have earlier demonstrated therapeutic effects of hydro-alcoholic leaf extract of WS on the age-induced alterations in the levels and daily rhythms of various clock genes such as rBmal1, rPer1, rPer2 and rCry1. We have now studied effects of hydro-alcoholic leaf extract of WS on the age-induced alterations in the levels and daily rhythms of expression of SIRT1 (an NAD+ dependent histone deacetylase and a modulator of clock) and NRF2 (a clock controlled gene and a master transcription factor regulating various endogenous antioxidant enzymes) in addition to rRev-erbα in SCN of adult [3 months (m)], middle-aged (12 m) and old-aged (24 m) male Wistar rats. The daily rhythms of rNrf2 expression showed 6 h phase delay in middle age and 12 h phase advance in old age. WS restored rSirt1 daily rhythms and phase in old age whereas it restored the phase of rNrf2 in the SCN of both middle and old aged animals. At protein level, SIRT1 expression showed phase advances in 12 m and 24 m whereas NRF2 daily rhythms were abolished in both the age groups. WS restored the phase and daily rhythms of SIRT1 as well as NRF2 in 12 m old rats. However, rRev-erbα expression was found insensitive to WS treatment in all the age groups studied. Pairwise correlation analysis demonstrated significant stoichiometric interactions among rSirt1, rNrf2 and rRev-erbα in 3 m which altered with aging significantly. WS treatment resulted in differential restorations of such interactions.
