RESUMO

The objective of this study was to analyze the diverse morphological attributes of Kotdhar goat native to Shivalik hill region of Himachal Pradesh. A total number of 180 goats, comprising 150 females and 30 males aged between 1 and 3 years, were randomly selected to estimate15 distinct morphological traits and ten body indices. Mean values of 17.66 cm, 11.68 cm, 8.73 cm, 71.94 cm, 69.83 cm, 74.48 cm, 38.10 cm, 73.38 cm, 20.55 cm, 16.48 cm, 14.89 cm, 13.57 cm, 19.20 cm, 7.71 cm and 26.12 kg were estimated for head length, head width, face length, body length, wither height, heart girth, chest depth, rump height, rump length, rump width, haunch width, bicoastal width, shoulder width, cannon bone and body weight respectively. In addition, morphological indices viz. body index, length index, body ratio, thoracic development, pelvic index, longitudinal pelvic index, transverse pelvic index, proportionality index, dactyl thorax index and relative depth of thorax were estimated from morphological traits. Results of morphological indices indicated that Kotdhar goat are medium bodied, longilinear, tall animals and well-suited for meat production. Phenotypic correlation among most of traits was positive and significant. Among all correlations, correlation between head length and head width was found lowest (- 0.270), while the correlation between heart girth and chest depth was observed highest (0.861). Canonical discriminant function analysis showed that there was no considerable level of intermixing for morphological traits in Kotdhar goat. Employing principal component analysis with varimax rotation, three principal components were observed, accounting for 68.47% of the total variation. First principal component (PC1) encapsulated the highest proportion of variance (44.39), revealing the high loadings on head length (0.777), body length (0.747), wither height (0.782), heart girth (0.785), chest depth (0.706), rump height (0.762), haunch width (0.734) and bicoastal width (0.793). Hence, it is possible to utilize these eight variables out of the 15 morphological traits for the characterization of the Kotdhar goat.

RESUMO

The pea leafminer, Chromatomyia horticola (Goureau) (Diptera: Agromyzidae) is a polyphagous and serious pest of peas. In India, this pest is attacked by many parasitoids and among them Diglyphus horticola Khan (Hymenoptera: Eulophidae) is an important one, however, demographics and pest-kill potential of this parasitoid has not been studied so far. This study presents the first report on its demographics and pest-kill potential on C. horticola. The parasitoid showed three modes of host-killing behaviour viz. host-feeding, parasitism and host-stinging. The parasitoid females killed more number of hosts by parasitism than host-feeding or host-stinging. The pre-adult survival, net reproductive rate, intrinsic rate of increase (rm) and finite rate of increase (λ) were higher on the 5-days old host larvae than those reared on the 3-days old larvae. Demographics and pest-kill parameters of D. horticola were also better on 5-days old host larvae than on 3-days old host larvae. Based on the study, D. horticola appeared to be a promising biocontrol agent for the suppression of C. horticola in peas and could be promoted through conservation biological control. Further studies are required to standardize the mass production protocol and release rates to use the parasitoid by augmentation.

RESUMO

The aim of the study was to examine the effects of repeated administrations of antioxidant multiminerals and vitamins in transition buffaloes on udder defense mechanism, antioxidant activity and occurrence of intramammary infection (IMI) in early lactation period. Forty clinically healthy pregnant buffaloes were enrolled 45 days before expected date of calving and randomly allocated into five different supplementation groups (n = 8): only basal ration (control), vitamin E and selenium (VES), multiminerals (MM), ascorbic acid (AA) and chromium (Cr) picolinate in basal diet. The udder defense mechanism was monitored by measuring phagocytic activity (PA), myeloperoxidase (MPO) and nitric oxide (NO) productions in milk leukocytes, antioxidant activity was evaluated by measuring total antioxidant capacity (TAC) in plasma and occurrence of IMI was assessed by milk cytology, bacterial count in milk and visible clinical signs of udder until day 28 post-calving. The results showed that the VES and MM supplementations exhibited significantly higher PA, MPO and NO productions of milk leukocytes till first week of lactation whereas, elevated mean TAC in plasma was maintained from day -7 to 1 of calving in MM supplementation group as compared to control group. Statistically, no significant difference in occurrences of subclinical or clinical IMI was noted across the groups until four weeks of lactation. Taken together, it is concluded that repeated administrations of VES and MM to transition buffaloes could be an effective strategy to maintain good udder health by augmenting milk leukocyte functions and antioxidant status and preventing incidence of IMI in early lactation.

RESUMO

BACKGROUND & OBJECTIVE: A reliable and reproducible report from a laboratory needs internal quality control within the laboratory and participation in external proficiency testing programmes (EPTP). This study conducted at the Department of Haematology, All India Institute of Medical Sciences (AIIMS), New Delhi, which has been conducting an EPTP since 1992, was undertaken to assess the efficacy of this programme in improving the performance of participating laboratories in reporting test samples sent for Hb, total leucocyte count (TLC), reticulocyte count and assessment of peripheral blood smear (PBS). METHODS: The samples were prepared in our laboratory according to the International Standards Organization (ISO) guidelines. The performance of individual laboratories was assessed using robust Z score, which is an indicator of acceptability of the test result. RESULTS: An improvement in the overall percentage of laboratories with acceptable reports was seen during the study period. It has increased from 38,40,40 per cent in 1992 to 85, 90,94.7 per cent in 2006 for Hb, TLC, reticulocyte count, respectively. However, the results for peripheral smear assessment improved only marginally. INTERPRETATION & CONCLUSION: The external haematology proficiency testing programme run by our department for Hb, TLC, reticulocyte count, and peripheral blood smear assessment, has helped in improving the reporting standards of these parameters in Indian laboratories.

RESUMO

Chronic administration of clenbuterol, a beta-adrenoceptor agonist (2 mg/kg body weight/day for 30 days) to mice resulted in an increased body mass. Measurement of dry tissue mass suggested a protein anabolic effect in the gastrocnemius and heart. Quantitative estimation of collagen content, a non-contractile element as calculated from hydroxyproline assay revealed its proliferation in the gastrocnemius, cardiac ventricle, intestine and to some extent also in the kidney. Clenbuterol did not induce collagen proliferation in non-muscle tissues such as the lungs and liver. Histopathological examination of sections from treated ventricles showed an extensive collagen infiltration in the subendocardium and at myonecrosis sites.

RESUMO

The increased frequency of isolation of Pasteurella multocida capsular type B from rabbitries in north-western India prompted this investigation into the role of this organism in inducing disease in rabbits. Ten rabbits were divided into two groups of five animals. Group I rabbits were infected intranasally (IN) with 1 ml of inoculum containing 2 × 10(5) colony forming units/ml, while rabbits in group II were given 1 ml phosphate buffered saline IN. The rabbits in group I developed respiratory distress, increased rectal temperature and severe dyspnoea, with death occurring 24-48 h post infection. The main pathological findings were severe congestion and haemorrhage in the trachea, fibrinopurulent pneumonia, bacteraemia and septicaemia. The nasal secretions of all group I animals contained P. multocida. These observations indicate that in addition to P. multocida capsular types A and D, P. multocida capsular type B can also be highly pathogenic for rabbits.

RESUMO

We describe a modified surgical technique of anterior capsulotomy and phacoemulsification for use in hypermature cataracts. Surgical steps included inferior linear capsulotomy with aspiration of milky cortex, inflation of the capsular sac with viscoelastic, a reverse triangular anterior capsulotomy with Vannas scissors, and in-the-bag bimanual sculpting of the nucleus. An oval 5 mm x 6 mm posterior chamber intraocular lens was used with single horizontal or no-stitch wound closure. The technique was used successfully in 20 cases of hypermature cataract. The mean time required to perform phacoemulsification was 3.46 minutes (range 1.2 to 6.3 minutes), with a standard deviation of 1.29. Visual acuity on the first postoperative day ranged from 20/20 to 20/60 (median 20/40). At one week, the mean astigmatism was 1.01 diopters (range 0.25 to 2.75 diopters). The mean endothelial cell loss was 13% (range 3.6% to 26.0%). Based on our results, the modified phacoemulsification technique merits consideration for use in hypermature cataracts.

RESUMO

Expression of myosin heavy chain (MHC) was investigated in rat uterus during pregnancy. Two MHC isoforms, SM MHCI (204 kDa) and SM MHCII (200 kDa), were resolved following the analysis of Guba Straub extract of non-pregnant and pregnant uterus using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). Whereas SM MHCI showed an increase from 69.26 +/- 3.26% in nonpregnant uterus to 81.40 +/- 5.36% in pregnant uterus, the SM MHCII exhibited a corresponding decline from 30.73 +/- 3.29 to 18.59 +/- 5.36%. The native myosin separated under non-dissociating conditions and subsequently analyzed in denaturing SDS-PAGE also demonstrated two MHC isoforms with identical electrophoretic mobilities. A SDS-PAGE analysis of native myosin from pregnant rats extracted at room temperature and in the absence of proteolytic inhibitors revealed a characteristically increased proteolysis of MHC into two peptide products of 153 and 140 kDa during pregnancy. Such a proteolysis of MHC, but in very low proportions, was noticed in nonpregnant uterus too.

RESUMO

Stimulation of lamb tracheal smooth muscle fibre strips with endothelin-1 and okadaic acid results in the development of isometric tensions which are long lasting. However, endothelin-1 is more potent constrictor than okadaic acid. An analysis of 20,000 Da regulatory myosin light chain by two-dimensional gel electrophoresis shows an identical phosphorylation pattern.

RESUMO

Effects of isoproterenol on isometric force, and 20,000 Da myosin light chain (LC20) phosphorylation were examined in smooth muscle fibre strips from lamb trachea stimulated with endothelin-1 (ET-1). ET-1 induced a rapidly rising isometric tension which was coupled with a multiple site phosphorylation of LC20. Isoproterenol addition at the time of peak isometric force resulted in a brisk relaxation of the fibre strips. Myosin light chain phosphorylation, however, remained unaffected.

RESUMO

When compared with the standard free muscle grafts, predenervated and nerve crushed chick gastrocnemius muscle grafts followed an identical and ordered sequence of tissue degeneration-regeneration. Atrophy of the fibres during ischaemic degeneration was accompanied by loss of weight, noncollagenous proteins and increment in lytic enzymes (acid and alkaline phosphatase), glucose 6-phosphatase, glycogen and succinate dehydrogenase. Regeneration was more rapid in standard free muscle grafts. Trophic insults to muscle via denervation and nerve crushing prior to transplantation did not influence graft renewal when compared with standard free muscle grafts though relatively increased recovery was shown by predenervated muscle grafts.

RESUMO

Changes in the expression of native myosin, myosin heavy chains (MHCs) and myosin light chains (MLCs) were investigated in goat uterus during early pregnancy. Electrophoresis of native myosin under non dissociating conditions displayed two isozymes differing in their proportions during gestation. Three MHC isoforms were obtained following sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE). Whereas 204 kDa (a smooth muscle MHC) and 196 kDa (a non muscle MHC) were recorded in uterus from non pregnant goat, uterus of pregnant goat displayed a third 200 kDa smooth muscle MHC. Two conspicuous proteins (154 and 140 kDa respectively) in addition to MHCs were also obtained when the myofibrillar extracts were analysed either in the presence or absence of proteolytic inhibitors. Non pregnant goat uterus showed a basal level (ca.5%) of phosphorylation of regulatory myosin light chain. Uterine myosin from pregnant goat was recorded in a completely dephosphorylated state.

RESUMO

Endothelin-1 is a new potent vasoconstrictor peptide produced by the endothelial cells. The contractile effects of endothelin-1 (ET-1) were compared with those of cabachol in lamb tracheal smooth muscle. Equimolar concentrations (10(-6)M) of endothelin 1 and carbachol elicit rapidly rising isometric tension which is maintained indefinitely in a steady state when fibres are stimulated with carbachol. Fibre strips exposed to ET-1 cannot maintain peak isometric force beyond 15-20 min and instead these exhibit a decline in tension towards near relaxed state. In addition to an early transient relaxation, ET-1 stimulation results in a 20,000 Da myosin light chain phosphorylation pattern different from that of carbachol stimulation.

RESUMO

A comparative study of myosin light chains (MLCs) has been made in the aorta, uterine and cardiac muscles (auricle, ventricle) of mice, pig, sheep and goat. Analysis of myosin light chains by sodium dodecyl polyacrylamide gel electrophoresis (SDS-PAGE) has revealed that (a) aorta myosin from mice, goat and pig has identical myosin light chains profile but pig aorta myosin lacks LC-2f; (b) uterine smooth muscle myosin depicts absence of LC-1f in sheep. Whereas satellite bands of LC-1f and LC-2f fractions are absent in pig uterine myosin, mice shows duplets for both the myosin light chains; (c) the auricular myosin in pig and goat is identical to chicken gizzard myosin used as reference and exhibits ALC-2s and ALC-1s fractions only while sheep auricular myosin lacks in ALC-1f; (d) the mice ventricular myosin depicts two satellite MLCs associated with fast migrating VLC-1s.

RESUMO

Three skeletal muscles viz., gastrocnemius, pectoralis and diaphragm from rats acclimated to a low temperature (4 +/- 1 degrees C; 16 hr daily; maximum for 8 weeks) exhibit an increased myosin ATPase activity. An analysis of native myosin from these muscles under non-dissociating conditions reveals two myosin isozymes instead of a single isozyme expressed in control muscles. Isoelectric focusing (IEF) coupled with two dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (2-D SDS-PAGE) confirms an increased phosphorylation of myosin light chain 2 (MLC2) in muscles from cold acclimated rats.

RESUMO

Effects of uterine stretching and physiological hypertrophy on myosin isozyme were investigated in rat during pregnancy. Both nonpregnant and pregnant rat uteri express a single myosin band on native gels. Analysis of native myosin under denaturing conditions revealed two myosin heavy chains (MHCs) with molecular mass of 204 and 200 kDa respectively. Filamin, a 240 kDa protein co-electrophoreses with myosin on native gels. No correlation is found between regulatory myosin light chain phosphorylation and pattern of myosin isozymes or the MHC. The results suggest that uterine stretching and physiological hypertrophy during pregnancy do not induce any changes in uterine myosin isozyme.

RESUMO

Beta-agonists have skeletal muscle specific protein anabolic effects and are also known to cause cardiac hypertrophy. Changed total LDH and its isozymic patterns are conveniently employed for the detection of different pathophysiological states of the tissues. The purpose of this study is to confirm total LDH and its isozymic expression in ventricular tissue and serum in mice following oral administration of single but higher dose of isoproterenol (Iso) and clenbuterol (Cl) (100 mg/kg body wt. and 20 mg/kg body wt., respectively), after 4, 8 and 20 hours of drug administration. Mice heart witnessed increased total LDH levels with time. Serum on the other hand showed decline in total LDH concentrations at the initial points of the drug treatment. No doubt, total LDH expression increased towards 20th h post-drug treatment but this increase is mainly due to anaerobic isozymes, i.e. LDH4 and LDH5. The findings of the present study suggest that tissue damage is definitely caused by two beta-agonists after giving single dose for shorter time span (20 hours) and the impact of the damage varies from drug to drug. Increase in total LDH in serum is not due to release from heart but from some other tissues having anaerobic metabolism.

RESUMO

Caldesmon phosphorylation has been proposed to be involved in regulation of smooth muscle contraction. Mitogen-activated protein (MAP) kinase has been suggested to be the caldesmon kinase; stimulation-induced MAP kinase activation in intact vascular smooth muscle, however, has not been demonstrated. We measured temporal profiles of MAP kinase activation in response to histamine stimulation and membrane depolarization in intact swine carotid artery. Phosphotyrosine levels of 42- and 44-kDa MAP kinases were elevated during contraction in response to histamine or KCl. The temporal profile of MAP kinase activation/inactivation was similar to that for contraction/relaxation of the vascular tissue in response to KCl or histamine stimulation. MAP kinase activated during contractile stimulation phosphorylates caldesmon with a specific activity significantly greater than that for myelin basic protein-(95-98). We propose that MAP kinase is activated in response to all forms of contractile stimulation. We also suggest that activated MAP kinase phosphorylates and disinhibits the effects of caldesmon on actin-myosin interactions. This disinhibition allows an inherent level of myosin ATPase activity to be expressed.
