Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced vital capacity ratio (FEV1/FVC) and forced expiratory flow (FEF (25%-75%)) were obtained according to American Thoracic Society criteria. Exposure to cotton inhalable dust concentration was measured in accordance with National Institute of Occupational Safety and Health criteria. Mann Whitney U test was used for comparison among target groups and statistical significance of the study was set at p<0.05. Cough, phlegm and dyspnea was observed in 78%, 51% and 44% patients (workers) respectively.

This organism is also being used for oil adjuvanted (Montanide ISA 50 V2) vaccine for mass vaccination in cattle & buffaloes in Punjab, Pakistan. A study was conducted to study the impact of glycerol and dimethyl sulfoxide (DMSO) on persistence of P. multocida duringits course of storage at 0, 4 and – 20 °C. Pure seed of P .multocida was grown in Brain Heart Infusion(BHI) broth at pH 7.4 and incubated at 37 °C for 18 hrs. in shaking incubator. The growth was observed for its purity microscopically as well as culturing on MacConkey’s & Nutrient agar slants. The pure culture was divided into three parts. One part was added with 5 % sterilized DMSO (final concentration) and second part was added with 10 % sterilized DMSO (final concentration) and 15 % glycerine (final concentration) while third part was kept as control without addition of DMSO and glycerine. All three parts were aliquoted (1 mL) in sterilized 1.5 mL eppendroff tubes and stored at three different temperatures i.e 0, 4 and – 20 °C. Eppendroff tubes from different temperatures were thawed in water bath (22 °C) and subjected to direct culturing on BHI broth, microscopic examination, purity testing on slants, culture turbidity / Optical Density (OD) values, dry biomass calculation and mice inoculation test for three months with 15 days intervals. The results indicated that pure P. multocida culture mixed with 10 % sterilized DMSO and 15 % sterilized glycerol stored at – 20 °C survived for three months and can be used for HS vaccine production without losing its survival.","PeriodicalId":19787,"journal":{"name":"Pakistan journal of science","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86169462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leaves suspension of C. occidentalis (250mg/kg) were used for the elimination of iron from iron overloaded rabbits. Rabbits were divided into three groups; overloaded for five weeks and then treated with selected herb for four weeks. Iron concentrations in serum and body organs like heart, liver and kidneys were assayed in all groups of rabbits after iron overloading with jectosol plus injections as per dose of 0.3 ml (15 mg iron) per kg body weight intramuscularly daily for 5 weeks. There was a significant increase in iron concentration in the sera and organs studied. In iron overloaded animals changes, like loss of weight, loss of hair, loss of activity and increased heart rate were observed. After four weeks of herbal treatment (250mg/kg), there was a significant decrease in iron concentration in the serum and organs as compared with iron overloaded untreated with herb group. The decrease was more significant in kidneys and liver as compared to the heart.

The field study was conducted to determine the influence of zinc on growth and yield of maize hybrid under skipping irrigations at different growth stages. The experiment comprised of two factors, irrigation treatment viz regular irrigation system (8 irrigations, control) and skip irrigation at knee high and tasseling stages and Zn application treatments i.e. non-Zn application as control, soil application @ 9, 18 and 27 kg ha-1. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement having three replications. The results showed that application of zinc @ 27 kg ha-1 gave maximum leaf area index (5.16), crop growth rate (20.26 g m-2 day-1), 1000-grain weight (255.03 g), grain yield (5.64 t ha-1) and harvest index (34.5%) than lower doses of zinc and minimum was recorded for control treatment. Similarly, for skipping irrigations, maximum improvement in growth and yield was observed with full irrigations, while irrigation skipped at tasseling stage negatively influenced the growth and yield of hybrid maize than at knee height stage. In conclusion, soil applied zinc at 27 kg ha-1 and normal irrigations helped in improving the growth and yield of autumn planted maize. \u0000 \u0000 \u0000","PeriodicalId":19787,"journal":{"name":"Pakistan journal of science","volume":"116 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87839230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
