The Chaga mushroom (Inonotus obliquus) has been used in folk medicine to treat cancers. However, limited information exists on the underlying anticancer effects of the major component of I. obliquusin vivo. We hypothesize that the pure compounds (3beta-hydroxy-lanosta-8,24-dien-21-al, inotodiol and lanosterol, respectively) separated from I. obliquus would inhibit tumor growth in Balbc/c mice b...

To evaluate whether the rectal route of immunization may be used to provide appropriate protection against enteric pathogens such as rotaviruses (RV), we studied the antibody response and the protection induced by rectal immunization of mice with RV virus-like particles (VLP). For this purpose, 6-week-old BALBc mice were rectally immunized twice with RV 8-2/6/7-VLP derived from the bovine RV RF...

The mouse is the most extensively studied animal species in respiratory research, yet the technologies available to assess airway function in conscious mice are not universally accepted. We hypothesized that whole body plethysmography employing noninvasive restraint (RWBP) could be used to quantify specific airway resistance (sRaw-RWBP) and airway responsiveness in conscious mice. Methacholine ...

BACKGROUND AND PURPOSE Animal models developed in rats and mice have become indispensable in preclinical cerebrovascular research. Points of interest include the investigation of the vascular bed and the morphology and function of the arterial, capillary, and venous vessels. Because of their extremely small caliber, in vivo examination of these vessels is extremely difficult. In the present stu...

Objective: The study was conducted to evaluate the effects of lead acetate and protective role of garlic extract on the histomorphology of the ovarian follicles in an animal model. Study Design: Laboratory based randomized control trial Place and Duration of Study: Department of Anatomy, Army Medical College in collaboration with National Institute of Health from April—June 2013 Material and Me...

OBJECTIVE To observe the effects of lead acetate and protective role of garlic extract on the histomorphology of the ovary in an animal model. METHODS The experimental trial was conducted at the Department of Anatomy, Army Medical College Rawalpindi, in association with the National Institute of Health (NIH), Islamabad, from April to June 2013. It comprised 30 adult non-pregnant female mice (...

BACKGROUND Despite its reported pro-inflammatory activity, cyclooxygenase (COX)-2 has been proposed to play a protective role in asthma. Accordingly, COX-2 might be down-regulated in the airway cells of asthmatics. This, together with results of experiments to assess the impact of COX-2 blockade in ovalbumin (OVA)-sensitized mice in vivo, led us to propose a novel experimental approach using ho...

one of the mechanisms involved in the regulation of the immune system by steroid hormones could be the monocytic-macrophage system. in this study the effect of the male hormone 5a-dht on cytokine release by peritoneal macrophages (mφ) of male and female nzb/balbc mice was investigated. macrophages from male mice activated with lps produced a greater amount of il-1β (21.8%) (p<0.05) and il-6 (19...

Cirrhosis is the final outcome of liver fibrosis. Kupffer cell-mediated hepatic inflammation is considered to aggravate liver injury and fibrosis. Alternatively-activated macrophages are able to control chronic inflammatory events and trigger wound healing processes. Nevertheless, the role of alternative Kupffer cell activation in liver harm is largely unclear. Thus, we evaluated the participat...
