Seed Yield and Quality of Broccoli as Affected by Different Levels of Nitrogen and Boron, and Main Head Harvesting in Plain Areas of Chitwan.

A study was conducted during the winter season of 2011/12 to find out the suitable measures for quality seed production of broccoli cv. Calabrese. The experiment was laid out in three factorial RCBD with three replications. Treatments consisted of four levels of nitrogenous fertilizer viz. 100, 150, 200, 250 kg ha-1 N, two levels of Boron viz. 15 kg ha-1 borax and no borax, two levels of head harvesting viz. head harvest at marketable stage and no head harvest. The results revealed that nitrogen levels, application of boron and head harvest significantly influenced the seed yield of broccoli. The highest seed yield (1296 kg ha-1) was obtained with 200 kg ha-1 N applied along with 15 kg ha-1 borax and main head harvesting. The seed quality parameters like test weight, germination percent and vigor index were also influenced by treatments. Significantly higher test weight was obtained with 200 kg ha-1 N, borax @ 15 kg ha-1 and head harvesting. Similarly, germination percent and vigor index of seed were significantly higher with 150- 200 kg ha-1 N application, borax @ 15 kg ha-1 and harvesting of main head. Comparing these treatments nitrogen 200 kg ha-1 along with borax 15 kg ha-1 and main head harvesting was found superior and economical for seed production of broccoli with B:C ratio of 4.79.

Pseudoexfoliation syndrome in various ethnic population of Nepal.

Pseudoexfoliation syndrome is an ocular condition characterized by a distinctive deposition of fibrillar material in the anterior segment of the eye. Pseudoexfoliation syndrome is frequently associated with glaucoma. Though it is seen in all the population, prevalence varies considerably in different races. A hospital based study done in Nepal by our group showed that Gurung population is frequently affected by this disease than any others. To determine the fact a larger population based study was necessary. Thus a research was designed to survey the various populations in the community. Different population from Kathmandu valley, Kavrepalanchowk, Pokhara, and Ghandruk were evaluated in two different phases to include major ethnic population living in Nepal. Household surveys done to bring all the targeted population to base hospital and detail examination including anterior segment evaluation after dilatation of pupil, optic disc evaluation, intraocular pressure measurement, gonioscopy, visual field recording and photographic documentation was done. Total of4430 population surveyed while only 2135 fulfilled the criteria for inclusion. Gurungs irrespective of their place of residence showed higher prevalence of Pseudoexfoliation syndrome accounting for 7.8% in Kathmandu valley while 12.0% in Ghandruk. Tamangs were affected very rarely by this disease accounting only for 0.3%. Gurungs are at higher risk of developing Pseudoexfoliation syndrome than any others in Nepal.

Association of primary glaucomas with retinal vein occlusion.

AIMS AND OBJECTIVES: To determine the association of Primary glaucoma with retinal vein occlusion. METHODOLOGY: A prospective cross-sectional study was carried out in B.P. Koirala Lions Centre for Ophthalmic Studies from April 2002-July 2003. All diagnosed cases of retinal vein occlusion were evaluated in detail for the presence of primary glaucoma. Detailed history was taken. Best corrected visual acuity was recorded, slit-lamp evaluation of anterior segment was performed, intraocular pressure was assessed with the help of applanation tonometer, gonioscopy was done and fundus evaluation was done under full mydriasis. RESULTS: Out of 50 patients, 19 (38%) were central retinal vein occlusion and 31(62%) were branch retinal vein occlusion. Majority of the retinal vein occlusion patients were in the age group of (61-70 years) 12 out of 50 patients (24%). There were 12 patients of primary glaucoma in 50 patients of retinal vein occlusion. Out of which 11 patients had primary open angle glaucoma and 1 patient had primary angle closure glaucoma. CONCLUSION: This study shows association of primary glaucoma as a risk factor of retinal vein occlusion. Evaluation of retinal vein occlusion patients for primary glaucoma would be worthwhile for early detection and prevention of blindness.

Prevalence of refractive error in mentally retarded students of Kathmandu Valley.

Mental retardation also known as 'mentally handicap' means a delay or insufficient development of mental capacities. The prevalence of mental retardation in Nepal is 4.1%. Vision being the best sense for their education and daily activities, a cross-sectional and descriptive study was conducted to find out the refractive error among the students in the schools for mentally retarded people. A total of 134 clinically diagnosed cases of mentally retarded students from three different schools of Kathmandu Valley were examined. Distance visual acuity was taken with the help of Cat Ford Vision Drum, SG chart and Kay Picture Test method but first preference was given to SG chart. Cyclo-retinoscopy and fundus examination under mydriasis were done in all the cases. Examination revealed that more than half of the examined had one or more ocular disorders with refractive error being the most common type of ocular morbidity followed by ocular motility disorders. Refractive errors were found in 34.4% in which the most common type of refractive error was simple hypermetropia. In conclusion refractive error was seen commonly among mentally retarded people of Kathmandu Valley.

Mandibular reconstruction.

One of the most difficult problem in reconstructive surgery is the replacement of lost bone from trauma, tumour, infection or congenital anomaly. This is a case report of a 20 year old male who had suffered a blast injury of his lower jaw. From his first admission in the Plastic unit of Bir Hospital on Feb 19, 2003, he had undergone multiple operations until Nov 2003. This is a description of a follow up surgery done in Kathmandu Medical College (KMC), Sinamangal. Difficulties encountered and options available have also been discussed.

Clinical profile and antibiotics response in typhoid fever.

OBJECTIVE: The objective of this study is to evaluate the clinical profile and drug response in typhoid fever. METHODS: This is a retrospective analysis of paediatric patients suffering from typhoid fever who were admitted at Kathmandu Medical College Teaching Hospital, Sinamangal during the period of two years and nine months. RESULTS: Total numbers of 100 cases of typhoid were studied. Diagnosis of Typhoid fever was based on clinical features, Widal test and blood culture. The sensitivity pattern of drugs in blood culture was recorded. The mode of presentation, treatment history, laboratory investigations reports, antibiotics administered and response to therapy were recorded. CONCLUSION: Quinolone is still the highly sensitive drug and most widely used for Salmonella typhi. Because of the indiscriminate use of these drugs, resistant to ciprofloxacin has been quite high and the duration of the defeverscence period has also been prolonged. But Ofloxacin is still showed highly effective and widely used with good response.

Nutritional status and morbidity pattern among governmental primary school children in the Eastern Nepal.

OBJECTIVE: To assess the nutritional status and morbidity pattern of primary school children. METHODS: Descriptive, cross sectional study was administered in the five governmental schools located in Dhankuta town (Dhankuta district) and Ineruwa town (Sunsari district). The schools were selected using simple random sampling technique. From these selected schools, a total number of 818 students studying from Grade I to V were enumerated in the study using census survey method. RESULTS: Among 818 students, 61% of the students were found to be malnourished. The students were more stunted (21.5%) than wasted (10.4%). Only 5.4 % of the students were found to be both wasted and stunted. The collected blood and stool samples from the students revealed parasitic infestation of 65.8% and anaemia of 58%. The most common diseases in those schools were: skin diseases (20%), dental caries (19.8%), and lymphodenopathy (10.5%). Among skin diseases, pediculosis was more common among girls while ringworms and scabies were common among boys. CONCLUSION: The study revealed that high percentage of primary school students was malnourished. It was found that there was a high prevalence of parasitic infestation and anaemia. The study result revealed the urgent need for initiation of school health program with specific emphasis on prevention of diseases, improvement of personal hygiene and nutritional status with the collaboration of governmental and non governmental institutions.
