  • The immune responses of commercial layer chickens against Newcastle disease (ND) were compared among different administration methods and times of vaccination during 4 weeks of age. A total of 372 day-old chickens were devided into 4 groups of 93 birds each. Each of 3 groups was received a commercially available B$_1$ live vaccine via drinking water, eye instillation or spray method at one, 14 and 28 days of age. One group was used as an unvaccinated control. At two and 4 weeks after each time of vaccination, 15 birds from each group were challenged with virulent ND virus at the dose of 10$^{5}$ EID$_{50}$ per bird to examine the pretection rate. Ten to 15 birds from each group were bled at two weeks intervals from day old to 8 weeks of age to determine hemagglutination inhibition antibody titer. The protection rate was generally low regardless of the times of vaccination although two or more times vaccination gave higher protection than once vaccination. The low protection was considered due to low titer of the vaccine used since the vaccine titer was less than 10$^{2.5}$ EID$_{50}$ per bird. Spray method gave better protection compared to eye instillation of drinking water method which resulted in lowest response. When birds were challenged majority showed clinical signs on ND between 3 and 6 days after challenge. Death occured one or two days after onset of symptoms. Major clinical signs observed were depression (96%), drowsy(90%), anorexia (84%), diarrhoea (29%), difficult breath (15%) and torticollis (10%). Hemorrhagic lesions on post mortem were seen in duodenum (51%), trachea(36%), illeum (13%), ceacal tonsil (11%), proventriculus (10%) and some other organs.

  • Piglet health at weaning is compromised due to several stress factors. Following the ban of antibiotic growth promoters new alternatives are required to control these problems. This paper reviews the evidence available for the use of spray dried animal plasma (SDAP) as an alternative to antibiotics in weaning pigs. Data from 75 trials in 43 publications involving over 12,000 piglets (mean values) have been used to calculate the performance responses of piglets according to several factors including SDAP origin, protein source from the control diet being replaced, dose of inclusion, age and weight of the piglets at weaning, sanitary conditions and simultaneous use or not of medication. Although the use of SDAP of all origins results in positive responses, it appears that plasma from porcine origin has the highest efficacy. This could be explained by the specificity of its IgG against porcine pathogens. During the first week post-weaning the response to plasma appears to increase with the inclusion dose, although over the two-week pre-starter period an optimal inclusion level of 4-8% is suggested. SDAP improves feed efficiency more markedly when the piglets are challenged with an experimental infection or when feed does not contain medication, which could be indicative of a lower expenditure of energy and nutrients to build an immune response against the challenge. There is evidence supporting that SDAP IgG and other bioactive substances therein prevent the binding of pathogens to the gut wall and reduce the incidence of diarrhoea in the post-weaning phase. Overall, plasma can be postulated as an excellent alternative to in-feed antimicrobials for piglets in the post-weaning phase.

  • Anaerobic rumen microorganisms mainly bacteria, protozoa and fungi degrade ligno-cellulosic feeds consumed by the ruminants. The ruminants in developing countries are predominantly maintained on low grade roughage and grazing on degraded range land resulting in their poor nutrient utilization and productivity. Hence, manipulation of rumen fermentation was tried during last two decades to optimize ruminal fermentation for improving nutrient utilization and productivity of the animals. Modification of rumen microbial composition and their activity was attempted by using chemical additives those selectively effect rumen microbes, introduction of naturally occurring or genetically modified foreign microbes into the rumen and genetically manipulation of existing microbes in the rumen ecosystem. Accordingly, rumen protozoa were eliminated by defaunation for reducing ruminal methane production and increasing protein outflow in the intestine, resulting in improve growth and feed conversion efficiency of the animals. Further, Interspecies trans-inoculation of rumen microbes was also successfully used for annulment of dietary toxic factor. Additionally, probiotics of bacterial and yeast origin have been used in animal feeding to stabilize rumen fermentation, reduced incidence of diarrhoea and thus improving growth and feed conversion efficiency of young stalk. It is envisaged that genetic manipulation of rumen microorganisms has enormous research potential in developing countries. In view of feed resource availability more emphasis has to be given for manipulating rumen fermentation to increase cellulolytic activity for efficient utilization of low grade roughage.

  • A total of 135 freshwater fish samples (Oreochromis spp. <85> and Clarias lazera <50>) were collected from different localities (shops and fish markets) in Alexandria Province-Egypt and examined for the presence of parasitic larval stages. The obtained data found the overall mean of the infestation with encysted metacercariae was 71.1% in the examined fish. The rates of infestation with encysted metacercariae were 72.9% and 68.0% in the examined Oreochromis spp. and Clarias lazera, respectively. The highest prevalence of the encysted metacercariae was found in summer (81.8%) in case of Oreochromis spp. and in winter (92.3%) in case of Clarias lazera, all these seasonal differences are statistically significant. The rate of infestation of encysted metacercariae in the anterior third, middle third and posterior third of Oreochromis spp. was found to be 82.3%, 74.2% and 95.2%, respectively, while 88.2%, 88.2% and 91.2%, respectively, in Clarias lazera. Moreover, the rate of infestation of encysted metacercariae in eyes, gills, liver, kidney and branchial cavity of Oreochromis spp. was 91.9%, 70.9%, 20.9%, 46.8% and 32.2%, respectively. In Clarias lazera the infestation rate was found to be 47.1%, 70.6%, 8.8% and 38.2% in the gills, liver, spleen and kidney, respectively. The zoonotic and public health importance of the encysted metacercariae are causes severe visceral pain, abdominal discomfort, intermittent bloody diarrhoea and colic after consumption of inadequately cooked fish especially Tilapia spp. (Oreochromis spp.).

  • Crocin was extracted from Gardenia fructus in order to manufacture a natural food dye. In the extraction and purification process methanol and ethanol were used as the most Suitable solvent selected in preliminary test and 9.28%g/100g of Cretin product in 99.89% of purity was acquired. The lethal dose of Cretin administered in mouse by intra peridoneal was 5.36g/kg which is much lower toxic than any other. The toxic dose which caused diarrhoea in rat was 2.55g/kg and maximum no effect level was found to be 272mg/kg. From the $1%{\sim}2.5%$ content of Crocin in rat diet reduction of body weight appeared and GTP and GOT (Transaminase) value in creased significantly. Crocin showed a good properties of tolerating acid, alkali, sunlight, reductant, oxidant, and salt compared with tar dyes. The range from 100 ppm to 500ppm bring out bright $yellow{\sim}orange$ color, the most effective color, with a good solubility in water-slightly in oil. The acceptable daily intake of crocin was calculated as 2.72mg/kg based on maximum no effect dose (2% additive dose).

  • The ethanol extract of leaves of the mangrove Aegiceras corniculatum Blanco (Myrsinaceae) was screened for its antinociceptive, antidiarrhoeal and cytotoxic activities. The extract produced significant writhing inhibition in acetic acid-induced writhing in mice at the oral dose of 250 and 500 mg/kg body weight (P < 0.001), which was comparable to the standard drug diclofenac sodium at the dose of 25 mg/kg of body weight. When tested for its antidiarrhoeal effects on castor oil induced diarrhoea in mice, it increased mean latent period and decreased the frequency of defecation significantly at the oral dose of 500 mg/kg body weight (P<0.05; P<0.01) comparable to the standard drug loperamide at the dose of 50 mg/kg of body weight. Moreover, when tested for toxicity using brine shrimp, the extract showed potent activity against the brine shrimp Artemia salina ($LC_{50}$ 10 mg/ml). The overall results tend to suggest the antinociceptive, antidiarrhoeal and cytotoxic activities of the extract.

  • Background: The purpose of this retrospectively study was to examine the effectiveness and tolerability of a radiotherapy technique for the palliation of symptomatic liver metastases. Materials and Methods: Twentyseven patients with liver metastases were enrolled and received targeted whole liver irradiation consisting of mean 1, 8 Gy in five to twelve fractions to a total mean dose 17Gy. Symptoms at baseline were hepatic pain (26 patients), lost of weight (6), lack of appetite (2), and night sweats (1). Seventeen patients (63%) had failed previous treatment with chemotherapy and/or high-dose steroids. Results: Individual symptom response rates were 100% at 4 weeks. Partial or complete global symptomatic responses were noted in 11 patients (40%) after 2 months. After 3 months, 8 patients (28%) reported loss of pain. The treatment was well tolerated with one patient (3%) experiencing grade 3 toxicity (one vomiting and one diarrhoea). Overall the median survival time was 4.9 months (range 1 - 14 months). One year survival was 39%. Conclusions: This is simple and well-tolerated treatment but to achieve good palliation effects we should carefully selected patients whose conventional treatment does not bring good analgesic control.

  • Traditional system of medicine mentioned the use of plants in treatment of various human ailments. Mochrus (Bombax ceiba Linn.) is one of the medicinal plants used in Unani medicine since time immemorial. It is a very tall tree with approximately 150 feet height. It is widely found in temperate Asia, tropical Asia, Africa and Australia. In India, it can be found at altitudes up to 1500 m. In peninsular India, the tree is very common in the dry as well as moist deciduous forests and near rivers. It is reported to possess qabiz (constipative); mujaffif (siccative); muqawwi rehm (uterine tonic); nafi sailan rehm (beneficial in leucorrhea); mumsik wa mughalliz mani (increase consistency of semen); muallide mani (production of semen); habise tams (amenorrhoic); dafi fasaad khoon wa safra (purifies blood and bile); taskeen hiddat aza (hotness of organs); muqawi asnan wa lissa (tonic to teeth and gums) etc. Ethnobotanical studies prove that it is used in diarrhoea, asthma, impotency, boils, wounds, leprosy, pimples and many other skin diseases. It is an anthelmintic remedy since ancient time. Pharmacological studies like hypotensive, antioxidant, analgesic, anti-inflammatory, antipyretic, antiangiogenic, anti- bacterial, cytotoxic, hepatoprotective, diuretic, anthelmintic, anticancer, spermatogenic and anti-helicobacter pylori activities have been evaluated for various parts of this plant that confirms to its use in classical medicine.

  • Ayurveda scholars have well described about the physio-anatomical aspect of mammary gland (Stana), physiology of lactation, importance of breast milk (Stanya) in growth and development of baby, various factors affecting the lactation and causing changes in property of milk, Galactogouge (Stanyajanana), and drugs for purification of mother milk (Stanya Shodhana). The recent studies provide evidence for above descriptions of Ayurveda. Breast milk (Stanya) is the nearly complete sole source of nourishment for infants. It has been considered as subsidiary tissue (Upadhatu) of blood plasma (Rasa Dhatu) as it is formed out of Rasa Dhatu (Plasma) and its quality and quantity gets affected by quality of nutrient fraction of food formed after complete digestion (Aahar Rasa). It provides health (Aarogya), strength and immunity (Bala) to the feeding child and gives innumerable beneficial effects like protection against not only acute infections like URTI, diarrhoea but also on chronic illnesses like CVD, metabolic disorders too. The Ayurveda description related to Mammary gland and physiology of lactation still need a better understanding for its implementation on promotion of health. Thus an attempt has been made to compile and analyze the view of Ayurveda scholars on Breast (Stana), Breast milk (Stanya) and physiological aspect of lactation as well as to draw a possible scientific understanding for the relevance.

  • Intravenous administration of hydro-methanolic extract of Cyperus scariosus (3-10 mg/kg) produced hypotensive and bradcardiac effects. These effects remianed unaltered in atropinized animals indicating that cardiovascular effects of the plant extract are not medliated through activation of muscarinic receptors. In the in vitro studies, it suppressed the spontaneous contractions of guinea-pig paired atria, rat ulterus and rabbit jejunum in a concentration-dependent (0.1-1 mg/ml) manner. It also inhibited histanmine or acetylcholine-induced contractions of guinea-pig ieum indicating non-sepcific spasmolytic action. In rabbit aorta, it inhibited norepinephrine $(10\;mu{M)}$ as well as $K^+$ (80mM)-induced contractions at similar concentrations (0.1-1 mg/ml). These data indicate that cyperus scariosus contains $Ca^{2+}$ channel blocker-like constituent(s) which may explain hypotensive effect observed in vivo and the general spasmolytic activity of plant explain its folkloric use in diarrhoea.
