carbosulfan (2,3-dihydro-2,2dimethyl-7-benzofuronyl [(dibutyl amino) thio] methyl] a carbamate insecticide and acaricide was administered orally at an effective dose of 48 mg/kg/day to albino mice for 5, 10, 20 and 30 days .control mice received similar quantities of olive oil. daily body weights were recorded and mice were sacrificed after 24 hours after the terminal exposure. the histologic e...

Background: Conventional treatments for breast cancer involve surgery followed by radiation and hormonal therapy and/or chemotherapy. Some of these treatments have toxic side effects. Because drugs used in chemotherapy affect both cancer and normal cells to varying degrees, researchers are currently developing targeted drugs that only attack cancer cells without affecting normal cells. One appr...

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...

Lung cancer remains the leading cause of death in cancer patients. Severe treatment side effects and late stage of disease at diagnosis continue to be an issue. We investigated whether local treatment using 2-diethylaminoethyl-dextran methyl methacrylate copolymer with p53 (DDMC-p53) with or without cisplatin and/or microwave ablation enhances disease control in BALBC mice. We used a Lewis lung...

This study evaluates the effects of anesthesia and fluid support on hemodynamic parameters of the mechanically ventilated mouse of four different strains. All experiments were performed at a similar surgical level of anesthesia, as indicated by the probing of the pedal withdrawal reflex. Three anesthetic regimens [fentanyl-fluanisone-midazolam (FFM), ketamine-medetomidine-atropine (KMA), and is...

Cholecystokinin (CCK) facilitates the process of satiation via activation of vagal afferent neurons innervating the upper gastrointestinal tract. Recent findings indicate CCK acts on these neurons via a ruthenium red (RuR) sensitive pathway that involves members of the vanilloid (V) subfamily of transient receptor potential (TRP) channels. To further test this mechanism, the mouse provides an i...

In response to light, the retinal pigment epithelium (RPE) generates a series of slow potentials that can be recorded as the c-wave, fast oscillation (FO), and light peak (LP) of the electroretinogram (ERG). As these potentials can be related to specific cellular events, they provide information about RPE function and how that may be altered by disease or experimental manipulation. In the prese...

(i) Objective: This study was conducted to analyze the effect of lead acetate on the serum estrogen and progesterone levels in adult mice and the role of garlic extract. (ii) Study Design: Laboratory based Randomized Control Trial. (iii) Place and duration of study: Anatomy Department, Army Medical College, Rawalpindi in collaboration with National Institute of health from April-June 2013. (iv)...

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...
