To evaluate its effect on tendon healing in horses and to compare It with compound of similar viscoelastic properties, a study was performed on 8 horses, using a model of ZigZag splitting injury in DDFT. Eight clinically normal horses were randomly divided into 2 groups under general anaesthesia tendon splitting was performed in ZigZag form in DDFT in one forelimb in all horses. Ulterasonographic examination after tendon splitting was performed and confirmed the same injuries in all tendons. Group A horses had sodium hyaluronate (NaH) gel (10mg /ml) into the site of injury every other days for five successive days. Group B horses had methylcellulose (MeS) gel Injection at the same site. Serial ultrasonographic examination was perfomed In 2 groups at 7, 14, 21, 28 and 60 days after last intralesional Injection. Horses were euthanatized after 14 weeks of stall rest Ultrasonographic evaluation revealed Improved tendon healing after NaH injection (P < 0.05). Histologically, the DDFT from the Nail treated limbs had reduced inflammatoiy cells Infiltration, Improved tendon structure and less intertendinous hemorrhage, treatment with MeS had no significant effect on tendon healing. Sodium hyaluronate, administered intralesionally appears to have a pharmacuetically beneficial action in this model of tendonitis. دانشگاه تهران 2008-2525 55 v. 2 no. 2000 https://jvr.ut.ac.ir/article_16715_9b99472206d2cca26a5eddccf4f78e9b.pdf دکتر غلامرضا نیکبخت بروجنی author محمدعلی طالبی author text article 2000 per Haematological values can help clinicians and experts for diagnosis of disease and some other researches (eg. breeding management).

Fordetermination the weaning, season, sex, and kind of birth effects on RBC , WBC, MCV, MCH, MCHC, PLT and differentiation table, we examined blood samples from 281 lambs, 180 rams and 582 ewes. These samples were examined by ‘Technicon Haematology One (H1) instrument. RBC, WBC, MCV, and differentiation table had significant differences between pre and post weaning. Season had cosidarble effects on haematological values of rams and ewes. Age affected WBC, RBC, HCT values of rams and WBC, Hb, and PLT values of ewes. Sex effects on neutrophils, monocytes and eosinophils values were significant. Most parameters of lambs differed with matured sheep. دانشگاه تهران 2008-2525 55 v. 2 no. 2000 https://jvr.ut.ac.ir/article_16716_5ac509b2feb1d6631b6277add7f8fe67.pdf دکتر علی اسلامی author دکتر بهنام مشکی author text article 2000 per In order to study the periodicity of microfilaria of Dirofilario immitis in a dog naturally infected with this parasite, blood samples are taken from saphen or cephalic vein in every hours of 3 consecutive days and night (72 times).

Ketamine with the dose of 1 mg / kg and xylazine with the dose of 0.5 mg / kg prepared in a syringe and injected in caudal epidural region (C1 - C2). The onset, duration and extent of analgesia evaluated after injection. Heart and respiratory rates and also rectal temperature were recorded on 0,5,15,30,60 minutes after injection. This combination caused excellent analgesia of the tail, perineal region, anus and vulva within 9 ± 2.3 minutes and lasted for more than 120 minutes observation period. Evaluation of analgesia was carried out by pin prick test. Heart rate decreased significantly from baseline after 15 minutes. Respiratory rate also reduced significantly after 30 minutes in comparison to baseline. Rectal temperature did not change significantly.

This is the first step in medical history and medical research, it is as old as man’s thinking. In this article we will express some aspects of a few medical discoveries specially in the last millennium. The most important medical basis was the theory of four humors or four natures established by Hippocrate, Galen and developed by Avicenna and Jorjani. Najib al Ddin Samarghandi one of the greatest iranian physician (Killed in 1221 A.D.) was the first scientist who did not care about this theory. After medical discoveries of Louis Pasteur and other savants the four humors theory abolished totally. Ibn Nafis Gharshi in 1242 about 300 years before Micael Servetus expresed the theory of the pulmonary circulation. W. Harway (1578-1657) discovered the blood circulation which was a fundamental basis for physiology. Ibn Gof (d. 1336) expressed anastomosis of arterioles and venules via small valves 4 centuries before M. Malpighi. Rhazes (d. 925) for the first time expressed his fermentation theory 900 years before Louis Pasteur, he said that a ferment in the blood is causal agent of smallpox. Pasteur and Koch in 19th century definitely indicated microbial agents of some infectious diseases. Rhazes wrote the first article on the subject of allergy and Biruni (1048 A.D) mentioned an antibody like theory. The use of liver from a rabid dog on a bitten wound preconised by Avicenna (d. 1038) is a practical application of serotherapy and vaccination. Edward Jenner in 1798 found that inoculation of cowpox has immunizing character against smallpox, then the method of vaccination was applicable. Several diseases were controlled after development of microbiological knowledge but new disease like AIDS was appeared with it’s terrible figure. The never ending struggle between patient and disease is still going on. We must prevent the• recurrence of the deadly diseases in man and animals with the best trying and wisdom. دانشگاه تهران 2008-2525 55 v. 2 no. 2000 https://jvr.ut.ac.ir/article_16733_136b1b8b5e8eef8ddcc9e2cc0309c64b.pdf
