Inheritance of resistance to lindane in a laboratory-selected strain of Tribolium castaneum (Herbst)
Studies on the inheritance of resistance to lindane in a laboratory-selected strain of Tribolium castaneum, by making crosses between the resistant and a susceptible strain, showed that resistance in this strain is controlled by an autosomally inherited single gene which is incompletely dominant. 相似文献

This article describes the surgical management of uterine torsion by midline celiotomy and cesarean section on 12 mares presented with signs of colic to a teaching veterinary hospital. The mares were either in full term of gestation (n = 7) or in advanced stage of pregnancy (n = 5). Six mares were in first parity. Uterine torsion was diagnosed by per rectal and per vaginal examinations. For surgical intervention, mares were anesthetized using a combination of xylazine (1.1 mg/kg) and ketamine (2.2 mg/kg), intravenously. After intubation, the animals were maintained on halothane (n = 4) or isoflurane (n = 8) inhalation anesthesia. Midline celiotomy was performed, and foals were delivered by cesarean section. In 11 mares, before closing the abdominal wound, the uterus was detorted manually and confirmed for its normal position. Both anesthetic protocols using halothane and isoflurane were found satisfactory for surgical correction of uterine torsion. After long-term follow-up, the study reported 75.0% (9/12) survival rate for mares. One mare was euthanized because of devitalized, necrosed, and adhered uterus to the abdominal wall. Of the nine surviving mares, seven were successfully bred. Three foals were born alive, and only one could survive on long-term basis. Of the nine dead foals, two had umbilical cord torsion. 相似文献

The abdominal ultrasonogram of a dog admitted for acute onset of collapse revealed an abnormally displaced left medial liver lobe with no blood flow. Surgical and histological findings confirmed the ultrasonographic diagnosis of left liver lobe torsion. Ultrasonographic findings were useful and probably sufficient for a correct diagnosis. 相似文献

Water contamination has reached an alarming state due to industrialization and urbanization and has become a worldwide issue. Dyes contaminate water and are addressed extensively by researchers. Various technologies and materials have been developed for the treatment of contaminated water. Among them, adsorption has attracted great attention due to its ease and cost-effective nature. In recent years, graphene-based composites have shown great potential for the removal of contaminants from water. The literature reveals the usefulness of composites of graphene with metal oxides, carbon derivatives, metal hybrids and polymers for the removal of organic dyes from contaminated water. In this review, efforts have been made to compile the studies on the removal of cationic and anionic dyes from water using graphene-based composites. 相似文献

Traumatic injuries of the penis result from kick-related injuries, and injuries during coitus or masturbation are reported as common causes of penile hematoma in horses. In the present report, mating for the first time in a 2-year-old colt resulted in penile hematoma. The animal had difficulty in passing urine and had paraphimosis. Under general anesthesia a stab was given to drain the hematoma, and hydrotherapy with cold water along with antibiotics and analgesics was advised. Early surgical intervention and drainage of the hematoma helped in resolving the condition and resulted in normal functioning of the penis. 相似文献

Objective: To evaluate clinical presentation of pathologic fractures associated with suspected or confirmed osteosarcoma in dogs and to assess treatment and survival times. Study design: Case series. Animals: Dogs (n=25) appendicular pathologic fracture. Methods: Medical records (January 1997–May 2008) of dogs with pathologic fracture associated with a suspected or confirmed osteosarcoma were reviewed. Dogs were included if they had radiographic evidence of a pathologic fracture and a presumptive or definitive diagnosis of osteosarcoma. Radiographic details, histopathology, and/or cytology findings were recorded. Overall median survival time (MST) and MST of treated dogs were calculated. Age, sex, breed, and other concurrent treatment were evaluated. Results: Rottweilers, Irish Wolfhounds, and Greyhounds were the most common breeds represented. Most dogs had minor trauma and 60% had lameness preceding the fracture. Most commonly, fractures were nondisplaced with minimal comminution. None of the dogs had radiographic evidence of pulmonary metastases at admission. Immediate (13 dogs; 52%) and delayed (4; 16%) euthanasia were performed. One dog was not treated and died 90 days after diagnosis. Three dogs (12%) were treated by amputation alone, 1 (4%) with amputation and chemotherapy, and 3 (12%) with internal fixation using an interlocking nail. Overall MST was 1 day (range, 0–623 days) and MST of treated dogs was 406.5 days. Histologic confirmation of osteosarcoma was available in all treated dogs and 6 euthanatized dogs. Conclusions: Treatment of pathologic fracture associated with presumptive osteosarcoma should be considered as an option to amputation or euthanasia if owners desire other options. 相似文献

Objectives: To (1) describe vascular distribution in the grossly intact canine cranial cruciate ligament (CCL) using immunohistochemical techniques specific to 2 components of blood vessels (factor VIII for endothelial cells, laminin for basement membrane); and (2) compare the vascularity in different areas of interest (craniomedial versus caudolateral bands; core versus epiligamentous regions; and proximal versus middle versus distal portions) in the intact normal canine CCL. Study Design: In vitro study. Animals: Large, mature dogs (n=7) of breeds prone to CCL disease that were euthanatized for nonorthopedic conditions. Methods: Intact CCL were collected from fresh canine cadavers free from stifle pathology. CCL tissue was processed for immunohistochemistry and stained for factor VIII and laminin. Vascular density was determined by histomorphometric analysis. Results: Specific vascular staining was sparsely identified throughout the CCL; however, the proximal portion of the CCL appears to have a greater number of vessels than the middle or distal portion of the ligament. Conclusions: The CCL is a hypovascular tissue and its vascular distribution is not homogeneous. 相似文献

Objective: To (1) determine the microanatomic vascular distribution in ruptured canine cranial cruciate ligaments (CCL) using specific vascular immunohistochemical techniques, and (2) compare vessel density between ruptured and intact canine CCL and between different areas of interest in ruptured CCL using histomorphometric analysis. Study Design: In vitro study. Animals: Dogs (n=41) admitted for surgical treatment of ruptured CCL and 19 dogs euthanatized for nonorthopedic conditions. Methods: Diseased (variable CCL rupture) and intact (normal control) CCL were processed for immunohistochemical staining specific to vessels (factor VIII, laminin). Mean vascular density was assessed and compared in areas of interest (torn end versus remaining core regions of CCL, proximal femoral versus distal tibial core CCL regions). Results: Ruptured CCL was more vascular than intact CCL; however there was no difference in vascular density between the torn end and the remaining core area of the ruptured CCL. Ruptured CCL was vascularized to a greater degree at the proximal portion than the distal portion of the CCL. Partially ruptured CCLs had a higher vessel density than completely ruptured CCLs. Conclusions: Vascular density is increased in diseased CCL compared with intact CCL. It remains to be determined whether this finding is associated with the cause of CCL rupture or is a result of CCL degeneration and rupture. 相似文献
