    ABSTRACT: Histomorphological studies were conducted on the thymus of 24 Aseel chicken of both sexes in three age groups viz., A (2 month) B (4 months) and C (6 months). Gross morphological parameters were studied immediately after collection of specimen and then the tissue samples were fixed in neutral buffered formalin, for routine tissue preparation technique for light microscopy. Gross morphological studies showed thymus located on parallel to the vagus nerve and internal jugular veins, having long chain of thymic lobes, on either side of neck. The number of lobes ranged from 7-9 on right side and 6-8 on left side of neck. The color of the thymus was pale white to yellowish white and the shape of the lobes of thymus was elongated and flattened. Histological structure of thymus showed regression of thymic lobules with increased number of Hassall's corpuscles with advancement of age. The range of length and width of thymic lobules was 621.02-747.87µm, 375.75-445.87µm, respectively among different age groups. There was significant (P<0.001) difference found in the length and width of thymic lobules among three age group. Statistically no significant difference was noted with respect to sex.

    ABSTRACT: The study was carried out to compare midline and flank approaches for ovariohysterectomy in cats. The following parameters were studied: age, weight, incision length, duration of operation (min), duration of wound healing (days), gross wound appearance, histological characterization of wound healing and complications. Cats were divided into two groups based on surgical approaches for ovariohysterectomy Group-F (Flank approach) and Group-M (Midline approach). Both groups were further sub-divided into two subgroups, each comprising of 6 cats, based on age. Thus, there were total four subgroups which were named as Fy, My, Fa, Ma. The cats in subgroup-Fy, My, Fa and Ma were aged about 7., respectively. The incision length was given shorter in subgroup-Fy than that of all subgroups of cats. The duration of operation was 23.50±1.31, 31.50±1.52, 24.50±1.48 and 28.33±0.92 min in subgroup-Fy, My, Fa and Ma, respectively. The duration of operation was significantly taken higher (P<0.05) in subgroup-My than other subgroups of cats. The wound healing period was 11.67±0.99, 14.84±0.95, 10.67±1.15 and 14.50±00.89 days in subgroup-Fy, My, Fa and Ma, respectively. The wound healing in sub-group-My and Ma, took significantly (P<0.05) more duration than other subgroups of cats. Gross changes like erythema, dehiscence and discharge after 18-24 hours of surgery scored significantly higher (P<0.05) 1.75, 0.50, 0.50 in subgroup-My, whereas swelling was scored significantly higher (P<0.05) in sub-group-Fa. Gross changes like swelling, erythema, dehiscence and discharge after 10-14 days of surgery were significantly (P˃0.05) not subsided in subgroup-My as compared to other subgroups of cats. Complications rate was higher (24%) in subgroup-My and Ma than subgroup-Fy and Fa, while subgroup-Fa found with minimum complications rate (3%). It is concluded that ovariohysterectomy through flank approach is superior to the midline approach due to convenience, reliability, faster healing, rapid recovery and less postoperative complications. Further, it is concluded that ovariohysterectomy is suitable to perform in adult cats.

    ABSTRACT: The study was carried out to determine the histological characterizations of wound healing in cats. For the purpose, 24 feral/stray with mean age of 7 to 33 months and body weight between 1.72 to 4.02 kg cats were selected and divided in 4 subgroups. Ovariohysterectomy was performed in all the cats. The cats operated through flank approach healed earlier and histological characterization showed better wound healing through flank in adult cats. All the cats did not heal on the 12th day, and the trend of healing showed bit maturation. Parameters studied are histological characterization of wound healing were acute inflammation, chronic inflammation, granulation tissue amount, granulation tissue amount and fibroblast maturation, collagen deposition, re-epithelization and neovascularization.

    ABSTRACT: The gross anatomical studies shows that mean length of right lobe was 3.64 cm, 5.61 cm and 7.88 cm; length of left lobe was 3.09 cm, 4.93 cm and 7.27 cm; width of right lobe was 1.74 cm, 2.61 cm and 3.67 cm; width of left lobe was 1.38 cm, 2.15 cm and 3.24 cm; thickness of right lobe was 1.30 cm, 1.81 cm and 2.37 cm; thickness of left lobe was 1.14 cm, 1.56 cm and 2.11 cm; circumference of right lobe was 3.40 cm, 5.41 cm and 7.47 cm; and circumference of left lobe was 3.20 cm, 5.16 cm and 7.18 cm. The difference in weight of fresh liver with and without gall bladder, length, width, thickness and circumference of right and left lobe of fresh liver of broiler from 2 nd to 6 th week was significant (P<0.05). Histological study showed that mean diameter of hepatocytes of liver of broiler from 2 nd , 4 th and 6 th week of age was 24.33 µm, 34.93 µm and 46.20 µm which was significant (P<0.05). The mean diameter of central vein of fresh liver of broiler from 2 nd 4 th and 6 th week of age was 715.53 µm, 718.87 µm and 723.13 µm which was non-significant (P>0.05). Anatomical study showed that mean weight of gall bladder of broiler from 2 nd , 4 th and 6 th week was 0.50 gm, 0.95 gm and 1.28 gm; length of gall bladder from dorsal to ventral side was 0.98 cm, 1.76 cm and 2.62 cm; width of gall bladder from lateral sides was 0.70 cm, 1.03 cm and 1.51 cm; thickness of gall bladder was 0.60 cm, 1.04 cm and 1.42 cm; circumference of gall bladder was 1.51 cm, 2.30 cm and 3.12 cm. The difference in weight, length, width, thickness and circumference of gall bladder of broiler from 2 nd to 6 th week was significant (P<0.05). Histological study showed that the thickness of tunica mucosa of gall bladder of broiler from 2 nd , 4 th and 6 th week was 749.3 µm, 856.0 µm and 976.93 µm; mean thickness of tunica muscularis was 668.67 µm, 768.1 µm and 876.67 µm; and mean thickness of tunicamucosa was 601.0 µm, 684.67 µm and 781.67 µm. The difference in thickness of tunica mucosa, muscularis and serosa of gall bladder of broiler from 2 nd to 6 th week was significant (P<0.05). The mean weight of fresh liver with and without gall bladder, length, width, thickness and circumference of right and left lobe of fresh liver of broiler was increased in 6 th week of broiler as compared to 2 nd week of broiler. The mean diameter of hepatocytes and central vein of fresh liver and of broiler were also increased in 6 th week of broiler as compared to 2 nd week of broiler. Similarly, weight, length, width, thickness and circumference of gall bladder of broiler were significantly increased in 6 th week of broiler as compared to 2 nd week of broiler. On the basis of above findings it can be concluded that age significantly affected the gross anatomical and micrometrical aspects of the liver and gall bladder of broiler.

    ABSTRACT: A total of 100 uteri from slaughtered buffaloes were studied at random. Eight different bacterial species were recognized, viz: Staphylococcus aureus, scherichia coli, Staphylococcus epidermidis, Corynebacterium pyogenes, Micrococcus citreus, Pr oteus mirabilis, Pseudomonas aer uginasa and Listeria monocytogenes. Of the uteri examined, 78 uteri were found positive for bacterial contamination, while 22 were free from every bacterial contamination. The percentage prevalence of the bacterial species was f ound to be 78%. The percentage incidence of individual bacterial species was also investigated. Staphylococcus aureus, Escherichia coli, Staphylococcus epidermidis, Corynebacterium pyogenes, Micrococcus citreus, Proteus mirabilis, Pseudomonas aeruginasa and Listeria monocytogenes were found with incidence of 23.07%, 17.94%, 14.10%, 14.10%, 11.53%, 8.97%, 6.41% and 3.84% respectively. The observations regarding pure and mixe d bacterial infections were also performed. The pure infection was recorded in 60 (76.92%) samples, while 18 (23.07%) were found carrying mixed bacterial infections with 3-4 bacterial species. Out of 78 positive uteri, 8(10.26%) were found containing pus. Out of 8 pyometric uteri, 2(25%) were carrying pure infection caused by Staphylococcus aureus and 6(75%) were carrying mixed infections with Staphylococcus aureus, Staphylococcus epidermidis, Micrococcus citreus and Corynebacterium pyogenes.
