Objective: To assess the yield of screening for asymptomatic carotid artery disease prior to isolated heart valve surgery (IHVS).

Methods: Retrospective analysis of the preoperative carotid duplex scans performed in neurologically asymptomatic patients who underwent IHVS between 2003 and 2006 was performed. Internal carotid artery (ICA) stenosis of 70% was considered significant. Patients with concomitant coronary artery disease were excluded.

Results: A total of 177 patients underwent IHVS (one valve in 165 and 2 valves in 12 patients). No or minor ICA disease detected in 172 patients. Four patients (2.25%) had significant unilateral ICA stenosis and 1 patient (0.56%) had unilateral ICA occlusion. Three patients (1.69%) suffered postoperative stroke, while 2 patients (1.1%) suffered transient ischemic attacks. All neurologically affected patients had normal preoperative carotid duplex. The in-hospital mortality was 4.5%.

Conclusion: Prevalence of significant ICA disease is low in patients undergoing IHVS. This population does not benefit from preoperative carotid screening.

  In view of domestication of the endangered species Nandus nandus, the artificial breeding of the fish with carp pituitary gland (PG) was trialed. The optimal dose of PG was found to be 150 mg kg–1 of fish body weight. Best fertilization rate (92±5%) was obtained at 175 and 200 mg kg–1 body weight PG application and best hatching rate (90±2, 90±5, 90±5%) was revealed at 150, 175 and 200 mg kg–1 body weight PG application. Fertilization and hatching rate were 92 and 81% respectively in case of the experiment where only females were injected. Ovulation occurred after 10 to 14 h of injection and the eggs hatched out after 18 to 20 h of fertilization. The larvae started feeding after 56 h of hatching and best survival rate (16%) was achieved by supplying zooplankton as food. It was also found that larvae denied egg yolk and Tubifex worm as their first food.

  Performance of nine selected wheat cultivars (Triticum aestivum L.) was studied during 1995-1996 under saline field environments at village Gundhari, distt. Nowshera. Site soil is recent river alluvium, sandy loam to clay loam in texture, slightly to highly saline and irrigated with tubewell water of 4 dS m–1. Two adjacent fields were surveyed by EM 38 at 2×2 m to identify areas of uniform salinity. Increase of root zone salinity decreased progressively all the plant traits including grain yield and yield component. Grain and straw yield were reduced by 69 and 64 percent respectively at the highest salinity level. Salinity tolerance ranking of cultivars based on absolute grain yield was SARC 3 > Bakhtawar 92 > Kharchia 65 > Blue Silver > SARC 1 > WS 10 > Mutant 1 > KTDH 10 > TW 161. Leaf Na increased, K and K/Na ratio decreased significantly with increase of root zone salinity. Sodium exclusion and K/Na discriminatory accumulation in leaf had contributed salt tolerance to wheat crop but these relationship could not be established in all cultivars.

  The present study was conducted on maize, with the aim to work out a suitable surface disinfecting procedure for seeds and to know the best concentration of 2,4-dichlorophenoxyacetic acid (2,4 -D) for callus induction in N6 medium using var. EV-2097. Better disinfection of seeds was achieved with 30 minutes Clorox treatment (86 %). Maximum callus induction (47 %) was recorded with 2 mg l-1 followed by 3 mg l-1 (18 %) and 1 mg l-1 2,4 -D (16 %).
