Effects of the hydro-ethanolic extract of Marrubium vulgare in female rats

OBJECTIVE@#To evaluate the effects of ethanol-water (80:20) extract of Marrubium vulgare (M. vulgare) on the hematological parameters, macroscopic and histological aspects of the uterus and fetus in non-pregnant and pregnant rats.@*METHODS@#Female rats were divided into 4 equal groups (n = 9), group N (normal rats) and group G (pregnant rats) considered as control groups, group NE (normal rats treated with the ethanol-water (80:20, v/v) extract of M. vulgare) and group GE (pregnant rats treated with the extract). The ethanol-water (80:20) plant extract was administered in a single daily dose 1 g/kg at the morning, during 19 d. On the 19 day of the experiment, animals were sacrificed, the uterus and fetuses were removed for the morphological and histological studies and the blood was collected in EDTA tubes for the measurement of hematological parameters with the use of an automate 'HORIBA ABX Micros 60 Hematology Analyzer'.@*RESULTS@#Our results showed, in group NE and GE, a significant decrease on hematological parameters: red blood cells (NE: 18.6%; GE: 38.4%), hematocrit (NE: 13.8%; GE: 20.4%), hemoglobin (NE: 12.1%; GE: 8.3%) and mean corpuscular volume (NE: 6.4%; GE: 2%) with P more less a 0.05. Indeed, the extract of M. vulgare caused a significant decrease on the mean implantations of fetuses (82.5%, P < 0.001) and their size (47.2%, P < 0.01). As for the macroscopic and histological appearance of uterus, our data showed no change in normal treated rats. In contrast, the treated pregnant rats showed a severe histological change characterized by the existence of location of stopped gestation. Furthermore, it was also found in the uterus of these rat lyses placental and embryo tissue.@*CONCLUSIONS@#All these results support the hypothesis of an abortifacient effect of M. vulgare.

[Liver regeneration after major hepatectomy, evaluation of dogs hepatectomy]

The aim of our study is to evaluate anatomic regeneration and metabolic derangement of the liver after major resection in dogs This is an experimental study on 9 dogs; we divided the dogs in two groups: the first group [5 dogs] underwent at one go major hepatectomy [90% of the liver].The second group [4 dogs] underwent successively a resection of 75% of the liver and a second resection of 90% of the restored liver six months later. All dogs underwent a metabolic and morphologic studies of the liver and of their kidney function In the first group; all dogs which underwent 90% hepatic resection died 48 hours after the surgical resection of hepatic insufficiency. The ultra microscopic study shoud the role of portal hypertension in hepatic degeneration on the first group. In the second group, the dogs survived the first resection, and our study shows a regeneration of the liver after resection and sub normal hepatic function The liver is able to regenerate after minimall resection but major resection must be done by successively resection to avoid hepatic dysfunction, but the time between resection must be evaluate later
