Objective: To investigate hepatoprotective activity of the methanolic extract of Fagonia indica Burm. on CCl4 induced hepatotoxicity in albino rats. Methods: Animals in Group 1 served as vehicle control, Group 2 served as hepatotoxin (CCl4 2ml/kg, s.c) treated group, Group 3 served as standard (Silymarin 50mg/kg, p.o.) treated group. Group4 and 5 served as methanolic extract of Fagonia indica (MEFI) in different doses (200 mg/kg and 400 mg/kg b.w., p.o).The degree of protection was determined by measuring levels of biochemical marker like SGOT, SGPT, ALP, Bilirubin (Total & Direct) and Cholesterol. The histopathological studies also show the hepatic protection of the test extracts. Results: The levels of the biochemical parameters such as SGPT, SGOT, ALP, Total bilirubin, Direct bilirubin and Cholesterol were significantly increased in CCl4 treated rats when compared with the normal group (P<0.05), but the MEFI (400 mg/kg, bw) treated rats showed maximum reduction of SGOT (114.83±1.51), SGPT (164.33±1.25), ALP (154.83±1.53), Total bilirubin (1.55±0.01), Direct bilirubin (0.65±0.009) and Cholesterol (193.00±1.06) in a significant manner. Histopathological studies also reveal the hepatoprotection property of MEFI in a dose dependent manner. Conclusions: These results suggest that MEFI in different doses showed significant hepatoprotective activity against CCl4 induced hepatotoxicity and this might be due to the presence of flavonoids and tannins. Further research is sought to explore the exact mechanism of action and phytoconstituents responsible for the pharmacological response.

A pig was confirmed to be a true hermaphrodite on the basis of gross and histomorphological studies of the genital organs. The genitalia was consisted of left ovary, oviduct, two coiled uterine horns, body of uterus alongwith right testis and an epididymis. Vagina and vulva were absent but male urethra with prostate gland was present. Grossly the size of all the genital organs appeared to be normal. Histomorphologically, testis and epididymis were underdeveloped as there was no clearcut spermatogenia and sertoli cells but Leydig cells were normal. The ovary presents normal histological features with some portion of testicular tissue. Degeneration of uterine epithelium was observed along with normal endometrial glands.

The animal model deals with the species other than the human, as it can imitate the disease progression, its’ diagnosis as well as a treatment similar to human. Discovery of a drug and/or component, equipment, their toxicological studies, dose, side effects are in vivo studied for future use in humans considering its’ ethical issues. Here lies the importance of the animal model for its enormous use in biomedical research. Animal models have many facets that mimic various disease conditions in humans like systemic autoimmune diseases, rheumatoid arthritis, epilepsy, Alzheimer’s disease, cardiovascular diseases, Atherosclerosis, diabetes, etc., and many more. Besides, the model has tremendous importance in drug development, development of medical devices, tissue engineering, wound healing, and bone and cartilage regeneration studies, as a model in vascular surgeries as well as the model for vertebral disc regeneration surgery. Though, all the models have some advantages as well as challenges, but, present review has emphasized the importance of various small and large animal models in pharmaceutical drug development, transgenic animal models, models for medical device developments, studies for various human diseases, bone and cartilage regeneration model, diabetic and burn wound model as well as surgical models like vascular surgeries and surgeries for intervertebral disc degeneration considering all the ethical issues of that specific animal model. Despite, the process of using the animal model has facilitated researchers to carry out the researches that would have been impossible to accomplish in human considering the ethical prohibitions.

Objective:
To quantify the extent of hyperlipidemia and its treatment in patients with stable coronary heart disease (CHD) or an acute coronary syndrome (ACS) in the Philippines.
Methods:
The Dyslipidemia International Study (DYSIS) II was an observational, multinational study conducted in patients aged ≥18 years with stable CHD or being hospitalized with an ACS. A full lipid profile was evaluated at baseline, and for the ACS cohort, at 4 months after discharge from hospital. Achievement of low-density lipoprotein cholesterol (LDL-C) targets and the use of lipid-lowering therapy (LLT) were assessed.
Results:
A total of 232 patients were enrolled from 10 centers in the Philippines, 184 with stable CHD and 48 being hospitalized with an ACS. The mean LDL-C level for the CHD patients was 88.0±40.1 mg/dL, with 33.3% achieving the target of <70 mg/dL recommended for very high-risk patients. For the ACS cohort, the mean LDL-C level was 109.0±48.5 mg/dL, with target attainment of 25.0%. The majority of the CHD cohort was being treated with LLT (97.3%), while 55.3% of the ACS patients were receiving LLT prior to hospitalization, rising to 100.0% at follow-up. There was little use of non-statins.
Conclusions
For these very high-risk patients from the Philippines, LDL-C target attainment was poor. Opportunities for better monitoring and treatment of these subjects are being missed.
