  The study was conducted to determine the composition of mineral content of cockle (Anadara granosa) shells from 3 major cockle cultivation of West Coast of Malaysia. Three samples of cockle shells from three different sources were evaluated to determine the content of 12 macro-and micro-elements (Calcium (Ca), Carbon (C), Magnesium (Mg), Sodium (Na), Phosphorus (P), Potassium (K), Ferum (Fe), Copper (Cu), Nickel ( Ni), Zink (Zn), Boron and Silica (Si)). For convenience and ease of reference, Ca and C were combine into one unit (Calcium Carbonate, CaC) while Mg, Na, P and K was evaluated individually and Fe, Cu, Ni, Zn, B and Si were evaluated as one group (others). Analysis of elements content was done using inductively Coupled plasma, Auto Analyzer, an Atomic Absorption Spectrophotometer and Carbon Analyzer. Results in this study revealed that the mineral compositions of cockle shells from 3 different sources in West Coast of Peninsular Malaysia were consistence almost in all the samples. The percentage of CaC comprises of more than 98.7% of the total minerals content of the cockle shells of the 3 sources. About 1.3 % of the composition are comprises of Mg, Na, P, K and others (Fe, Cu, Ni, B, Zn and Si).Overall, the minerals composition of cockle shells of West Coast of Peninsular Malaysia are as followed: CaC 98.7 %, Mg 0.05%, Na 0.9%, p 0.02 and others 0.2%.

  Pregnancy is associated with dramatic changes in morphological structure of endometrium and leucocytes infiltration within the uterus. The main aim of this study was to evaluate compare the histological structure of uterine mucosal of pregnant and non-pregnant rats. A total of eight healthy Spraque-dawley rats were used in this study. They were divided into two groups; pregnant and non-pregnant groups with 4 rats per group. For the pregnant group, the animals were euthanized at 14 days of gestation period. Uterine samples were taken and processed for histological examination using H&E staining and PAS stain for secretory cell count. Histological structure of the uterine mucosal layer of pregnant and non-pregnant rats was significantly difference. Infiltration of PMN cells was higher in non-pregnant rats than those of pregnant rats, whereas, infiltration of lymphocytes and macrophages were diffusely scattered in pregnant rather than the non-pregnant rats.

  The present study was conducted to evaluate the potential of cockle (Anadara granosa) shell as an alternative biomaterial for bone substitute. The cockle shells were cleaned thoroughly and dried in oven (50 C) for 3 days. The shells were then ground by using Blendor (240V) and sieved twice at 850 m and followed by 420 m. The powder was compressed to form dense pellet by using uniaxial compress technique. Three adult New Zealand White rabbits were used in this study. Each rabbit was implanted with cockle shell, cockle shell+binder and cockle shell+Hydroxiappatite (HA). The right and left gluteal muscles was implanted with cockle shell+binder and cockle shell+HA respectively, while the semitendinosus muscle was implanted with cockle shell. Radiography and ultrasonography techniques were used to evaluate the implant materials post-implantation. The animals were euthanased at three weeks post-implantation and samples of the implant materials and surrounding tissues were taken for histological evaluation. Result of the study revealed that after three weeks post-implantation, no new bone formation was detected. However, the ultrasound and the radiographic evaluations revealed the absorption and tissue reaction at the implantation sites.

  The present study was conducted with the aim to investigate the response of GALT following oral administration of P. multocida type B2. A total of 12 adults, Spraque-dawley rats, supplied by the animal breeding unit, Faculty of Veterinary Medicine, UPM, were used in this study. The rats were divided into 2 groups, which consist of 6 rats per group. 0.5 mL of 104 CFU of P. multocida B2 was given to the rats in first group through intranasal route by using 1 mL syringe while the second group was given 0.5 mL normal saline using the same method. Both groups were kept in cages separately for 2 weeks before being euthanased. The number and size of Peyerís patches of the intestine were counted and measured macroscopically upon euthanasation. The intestine was then divided into 14 portions; proximal, middle and distal of each the duodenum, jejunum, ileum and colon and one each for caecum and rectum for histological evaluation. The Hematoxylin and Eosin staining was used to count the number of lymphocytes follicles and intraepithelial lymphocytes. This stain also used to measure the size of lymphoid follicles. The Methyl Green Pyronin was used to count the number of plasma cell. The results showed that intranasal administration of Pasteurella multocida B2 has slight influence on the development of GALT. However, the different in the parameters study between control and infected groups were not significant (p>0.05).

  The study was conducted to evaluate the gross and histological appearances of fresh chicken carcasses between slaughtered and cervical dislocated methods. In this study, 5 adult broiler chickens with homogenous weight were slaughtered and another 5 chickens were cervically dislocated. The chickens were left at room temperature for 30 min prior to gross examination and sampling for histological examination. The gross appearance of muscle and internal organs was evaluated and compared. The internal organs were fixed with 10% formalin for 72 h before went through the process of dehydration, clearing, impregnation, embedding process into paraffin wax and process of sectioning and staining with Haematoxylin and Eosin. The sections were examined under light microscope. Results in this study revealed that the gross examination of the carcass killed by slaughtering method had showed pallor appearance as compared to the chickens killed by cervical dislocation method which appeared reddish in almost all of the organs. Histologically, there was no significant different in terms of distribution or composition of erythrocytes in the visceral organs except in lungs, kidney and liver where the chickens killed by slaughtering method contains less erythrocytes as compared to the chicken killed by cervical dislocation.

  This study was performed with the aim to evaluate the proximate, elemental and fatty acid analysis of pre-processed edible birdsí nests (Aerodramus fuciphagus) and their comparison between the regions and type of nests. The samples of edible birdsí nests were taken from 5 regions: 4 regions in Penang, Malaysia and one region in Sumatra, Indonesia. The nest type from regions in Penang was house nest, while the one from Sumatra was the cave nest. Analysis of total dry matter content was carried out according to the certification procedures outlined by the Manual of Livestock Feed Analysis, University Putra Malaysia. Crude protein was determined according to the Kjeldahl (micro) method. The fat content of the feed was determined using the total lipid extraction procedure. The crude fibre content of the sample was determined by using an automated apparatus. The elements analyzed in this study were Na, Ca, Mg, K, P and Fe. All of the elements were detected using the Atomic Absorption Spectrophotometer, while for P, PerkinElmer Lambda 35 Spectrophotometer was used. The results showed significant differences in proximate and elemental analysis of edible birdsí nests between the regions and nest types. There were no significant different in the fatty acid content of the nests both between the regions and the nests type. The results also showed that the edible bird-nest have essential components in promoting body vigour.

  The study was conducted to evaluate the macroscopic changes of burn wounds healing progress as a response to various types of honey applied topically. A total of 42 male, Sprague Dawley rats (weight 200-300 g) were used in this study. The animals were randomly divided into seven experimental groups consisted of 6 animals for each group. Macroscopic changes of the burn wounds healing progress were evaluated at day 0 post burned and subsequently at days 3, 7, 14, 21 and 28 post burned. To determine the rate of wound contraction the changes in the size of burn wounds were traced by measuring the diameter of the wound area both longitudinally and transversely across the body length using a ruler. The change in wound diameter at various time intervals was calculated as the percentage of wound area that had healed. The results obtained from this study indicated that topical application of Manuka and Melaleuca (Gelam) honeys significantly stimulated the rate of burn wound healing as assessed by increased in the rate of wound contraction and from the observation of gross appearances.
