Protective effects of alpha stone on monosodium glutamate-induced uterine hyperplasia in female wistar rats.

ABSTRACT: BACKGROUND:Uterine leiomyomas (fibroids), a menace of the reproductive age, is characterized by proliferation of smooth muscle cells (hyperplasia) of the uterus. Alpha Stone Decoction is a poly-herbal formulation that is used for the shrinkage and prevention of uterine fibroids in folkore medicine. OBJECTIVES:We investigated the efficacy and safety of Alpha Stone Decoction (ASD), on monosodium glutamate (MSG) induced uterine hyperplasia. MATERIALS AND METHODS:Twenty-eight mature virgin female rats were randomly divided into four study groups: A-control B- MSG (200 mg/kgbw), C- MSG + ASD (100 mg/kgbw) and D- ASD 100 mg/kgbw alone. The administration was carried out by as a single daily dose via intraperitoneal route for 14 days. Total protein, triglycerides, estradiol (estrogen), progesterone, and total cholesterol levels in sera were determined using appropriate kits. Uterine hyperplasia was assessed via histomorphometric method using the mitotic image plus software to compute the fibroblast cell count density while the uteri and ovaries of animals were stained with mason-tricon stain for histological examination. RESULTS:Administration of MSG for 14 days resulted heavy deposits of collagen connective tissue within the myometrium layers of the uteri. ASD significantly (p < 0.05) reduced fibroblast cell count in MSG-treated animals and also protected against MSG-induced damage observed in the myometrium of the uteri and ovaries of the animals. Significant increases (p < 0.05) in levels of total protein; triglycerides, progesterone, cholesterol and estrogen in the MSG-treated animals were ameliorated following administration of ASD. CONCLUSION:These findings suggest that ASD contains bioactive agents which reversed MSG-induced uterine hyperplasia. It may therefore be useful in reducing the proliferation of fibroblast cells and managing other symptoms associated with uterine myoma.

Project description:BACKGROUND:Osteoarthritis (OA) is an age-related joint disease with characteristics that involve the progressive degradation of articular cartilage and resulting chronic pain. Previously, we reported that Astragalus membranaceus and Lithospermum erythrorhizon showed significant anti-inflammatory and anti-osteoarthritis activities. The objective of this study was to examine the protective effects of ALM16, a new herbal mixture (7:3) of ethanol extracts of A. membranaceus and L. erythrorhizon, against OA in in vitro and in vivo models. METHODS:The levels of matrix metalloproteinase (MMP)-1, -3 and?-?13 and glycosaminoglycan (GAG) in interleukin (IL)-1? or ALM16 treated SW1353 cells were determined using an enzyme-linked immunosorbent and quantitative kit, respectively. In vivo, the anti-analgesic and anti-inflammatory activities of ALM16 were assessed via the acetic acid-induced writhing response and in a carrageenan-induced paw edema model in ICR mice, respectively. In addition, the chondroprotective effects of ALM16 were analyzed using a single-intra-articular injection of monosodium iodoacetate (MIA) in the right knee joint of Wister/ST rat. All samples were orally administered daily for 2 weeks starting 1?week after the MIA injection. The paw withdrawal threshold (PWT) in MIA-injected rats was measured by the von Frey test using the up-down method. Histopathological changes of the cartilage in OA rats were analyzed by hematoxylin and eosin (H&E) staining. RESULTS:ALM16 remarkably reduced the GAG degradation and MMP levels in IL-1? treated SW1353 cells. ALM16 markedly decreased the thickness of the paw edema and writhing response in a dose-dependent manner in mice. In the MIA-induced OA rat model, ALM16 significantly reduced the PWT compared to the control group. In particular, from histological observations, ALM16 showed clear improvement of OA lesions, such as the loss of necrotic chondrocytes and cartilage erosion of more than 200?mg/kg b.w., comparable to or better than a positive drug control (JOINS™, 200?mg/kg) in the cartilage of MIA-OA rats. CONCLUSIONS:Our results demonstrate that ALM16 has a strong chondroprotective effect against the OA model in vitro and in vivo, likely attributed to its anti-inflammatory activity and inhibition of MMP production.
