The study was conducted in ten buffalo calves, 1-2 years old,<br />

weighing 65 to 120 kg, r<strong>and</strong>omly divided into two groups of five<br />

animals each. Circulatory insufficiency (CI) was induced with<br />

thiopentone sodium (5%), <strong>and</strong> then in one group I, mephentermine<br />

(0.5 mg/kg, I.V.) <strong>and</strong> in group II, norepinephrine (2.0 mg<br />

norepinephrine in 500 ml normal saline solution equivalent to 4.0<br />

µg/ml, I.V. infusion) was administered for treatment. Various<br />

parameters investigated were: rectal temperature (RT), haemoglobin<br />

(Hb), plasma glucose, plasma creatinine, total plasma proteins, heart<br />

rate (HR), systolic pressure (SP), diastolic pressure (DP), mean<br />

arterial pressure (MAP), central venous pressure (CVP),<br />

electrocardiogram(ECG) electroencephalogram (EEG), arterial<br />

carbon dioxide tension (PaCO 2), arterial oxygen tension (PaO 2) <strong>and</strong><br />

venous oxygen tension (PvO 2).Restoration of corneal, palpebral<br />

reflexes <strong>and</strong> papillary reflex began within 15 minutes of<br />

mephentermine administration. The MAP was significantly elevated<br />

(21.06±1.191 kPa) five minutes after mephentermine as compared to<br />

5.99±0.794 kPa after CI <strong>and</strong> remained in the normal range<br />

(21.50±0.571 kPa). Following mephentermine administration highly<br />

elevated CVP (3.26±0.314kPa) was recorded during CI fell below<br />

the base line up to 15 minutes (0.76±0.027 kPa) <strong>and</strong> thereafter,<br />

remained in the normal range. Arterial O2 tension remained elevated<br />

(22.53±1.402 kPa) throughout the observation period. In the later<br />

stages of the experiment, there was mild decrease in the RT<br />

(36.7±0.29°C). Moderately elevated blood glucose levels during<br />

circulatory insufficiency (5.08±0.48 mmol/l) was further elevated by<br />

mephentermine administration (6.27±0.497 mmol/l). Corneal <strong>and</strong><br />

palpebral reflexes started returning by 45 to 60 minutes after the start<br />

of infusion of norepinephrine. Cardiovascular action of the<br />

norepinephrine started 1.19±0.28 minute after its initiation <strong>and</strong> near<br />

normal range of the arterial pressure could be achieved by 4.81±0.94<br />

minutes (15.27±0.853 kPa). The elevated CVP (3.43±0.495 kPa)<br />

during CI also decreased (2.04±0.197 kPa) after start of<br />

norepinephrine, but effect was slow as values remained significantly<br />

elevated than base line up to 15 minutes. Arterial O 2 tension<br />

remained elevated. The study revealed that mephentermine<br />

controlled the thiopentone induced CI effectively.<br />

Diagnosis <strong>and</strong> treatment of digital lesion in dairy cattle is important<br />

because of ample financial injuries. The bovine digit is a complex<br />

structure with many joints, ligament <strong>and</strong> tendons. Radiography (R)<br />

<strong>and</strong> Utrasonography (U) have a limited value in the evaluation of<br />

soft tissue. Computed tomography (CT) in small animal, is<br />

frequently used to evaluate the foot. The purpose of this research is<br />

provide a collection of normal cross-section anatomy of the bovine<br />

digit using by CT. CT was conducted on two hind limbs, taken from<br />

normal adult cows. CT was peformed using Siemens (ARTX MOD<br />

E1) at 50 mA <strong>and</strong> 130kv. The limbs were presented by freezing for<br />

several days at -18°C then the limbs sectioned in three planets<br />

transverse, sagital <strong>and</strong> dorsoplantar in 1- cm slices with an electric<br />

h<strong>and</strong>sow. The average CT- normal of the digits was 103. Identifiable<br />

anatomic structure was labeled on the line drawing of the limb<br />

sections <strong>and</strong> on the corresponding CT images. Images produced<br />

good delineation between cortex, medulla, corium <strong>and</strong> wall of the<br />

hoof. On CT image bone appeared hyper dense while tendons,<br />

ligament <strong>and</strong> wall of the hoof had similar shades of grey. Synovial<br />

fluid <strong>and</strong> blood vessels were hypo-dense. The dewclaws had a mixed<br />

opacity below the proximal phalanx. Average diameters of the deep<br />

digital flexor, superficial digital flexor, proximal sesamoidal bone,<br />

distal sesamoidal bone <strong>and</strong> phalanx were measured in all CT images.<br />

Since CT images are able to distinguish structures well, therefore it<br />

can use in distinction <strong>and</strong> effective treatment method of digit lesion<br />

in cow <strong>and</strong> the other animals.<br />

The aim of the present study was to determine different affections of<br />

the salivary ducts in buffaloes with special reference to diagnosis<br />

<strong>and</strong> treatment. The present work was carried out on a total number of<br />

35 buffaloes suffering form different affections of the salivary ducts.<br />

The majority of cases were collected during the periodical visits to<br />

veterinary clinics in 168 villages belong to 14 provinces in Egypt<br />

during the period from 1994 to 2007. Some cases were recorded in<br />

the veterinary teaching hospital of the faculty of veterinary medicine<br />

Assiut University. The recorded affections of the salivary ducts in<br />

buffaloes include; ectasia of the parotid duct (18), parotid duct<br />

fistula (14) <strong>and</strong> sialocele (3). Each case was subjected to full study<br />

including case history, clinical examination, diagnosis <strong>and</strong><br />

treatment, whenever possible. Exploratory puncture <strong>and</strong> radiography<br />

were used for confirmation of diagnosis in some cases. Intraoral<br />

marsupialization was performed for treatment of parotid duct ectasia<br />

with highly encouraging results. Salivary fistula was corrected by<br />

one of two successful techniques; the first by reconstruction of the<br />

parotid duct using polyethylene tube to preserve the function of the<br />

gl<strong>and</strong> <strong>and</strong> the second by ligation of the parotid duct just caudal to the<br />

fistual opening with nullifying the gl<strong>and</strong>s function. Sialoceles were<br />

corrected by removal of the m<strong>and</strong>ibular salivary gl<strong>and</strong> of the<br />

affected side in two animals only. The third animal was not operated<br />

by owner’s request. Successful results were obtained in one case<br />

only. The other case failed due to wrong side extirpation of the<br />

gl<strong>and</strong>. In conclusion we can state that salivary duct affections in<br />

buffaloes were ectasia of the parotid duct, salivary fistula <strong>and</strong><br />

sialocele. Treatment was available with successful results <strong>and</strong> good<br />

prognosis in ectasia of the parotid duct <strong>and</strong> salivary fistula <strong>and</strong><br />

guarded in sialoceles.<br />

The aim of the present study was to determine different kinds of<br />

cysts present on the body surface of some farm animals with special<br />

reference to diagnosis <strong>and</strong> treatment. The present work was carried<br />

out on a total number of 94 animals of different species<br />

(Buffaloes=5, Cattle=18, Sheep=5, Goat=34, Camel=13, Horse=5<br />

<strong>and</strong> Donkey=14) suffering from different kinds of cysts on the body<br />

surface. All cases were collected during periodical visits to<br />

veterinary clinics in 168 villages at 14 provinces in Egypt during the<br />

period from 1994 to 2007. Diagnosis was established depending on<br />

case history, location, clinical signs, exploratory puncture <strong>and</strong><br />

histopathological examination of excised cysts. Different kinds of<br />

cysts on the body surface were diagnosed namely; Dermoid (36),<br />

Branchial (7), Dentigerous (2), Tassel or Wattle (32), Thyroid (15)<br />

<strong>and</strong> Interdigital (2). Aspiration <strong>and</strong> injection of medicaments were<br />

performed for treatment of thyroid cysts; incision <strong>and</strong> evacuation<br />

were applied for treatment of dermoid cysts while surgical excision<br />

was done for many cysts such as branchial, dentigerous, tassel,<br />

interdigital <strong>and</strong> some dermoids. The results of treatment were<br />

encouraging without postoperative complications. In conclusion we<br />

can state that different varieties of cysts were observed on body<br />

surface in some farm animals <strong>and</strong> nearly all of them can be managed.<br />

The work was supplied by many colored photographs.<br />
