公猪鞘膜积液误诊为仔猪腹股沟阴囊疝手术疗法一例

猪腹股沟阴囊疝是兽医临床上常见的外科疾病之一,在民间俗称为疝气或通肠猪,具有一定的遗传性。猪腹股沟阴囊疝发生的主要原因是腹股沟环闭锁不全或撕裂,导致肠管等脏器脱落到腹股沟及阴囊内。2009年6月17日,我们在学校动物医院接诊了一头曾患有先天性腹股沟阴囊疝的小公猪,初诊为粘连性腹股沟阴囊疝,但经过手术治疗才确诊为小公猪鞘膜积液。

小公猪阴囊疝简易手术疗法

公猪的腹股沟阴囊疝有遗传性,常在出生时发生,或出生几个月后发生,而且多半见于一侧。也见于后天性的。常规阴囊疝的手术疗法是在疝孔(腹股沟环)位置切开皮肤及筋膜,把疝内容物纳回腹腔后,封闭疝孔,再按常规缝合筋膜与皮肤。此法疗效虽较确实,但操作较麻烦。笔者曾对二十余例患有阴囊疝的小公猪于去势的同时进行手术,成功率达100%。具体方法是: 由助手呈倒提姿势。术时,先把小肠送回腹腔,然后用中指、食指和拇指捏住阴囊颈部,把睾丸推向阴囊底部,使阴囊皮肤紧张,将睾丸固定。术者用右手持刀,沿

Experimentally induced testicular alterations in boars: hormonal changes in mature and peripubertal boars

Eleven sexually mature boars and 10 peripubertal boars were used to study the effects of elevated testicular temperature on plasma hormonal levels. The scrotum of the boars was covered with a textile-aluminium foil insulation device for 100 h. Insulation of the scrotum in the peripubertal boars took place at an age of 100 days. Blood samples were drawn 3 times daily for 12 days in the mature boars, starting 3 days before scrotal insulation. In the peripubertal boars, blood sampling was performed once a day for 11 days, starting the first day of scrotal insulation. During scrotal insulation, the plasma levels of testosterone, oestradiol-17 beta and oestrone sulphate decreased continuously in the mature boars. After removal of the scrotal insulation device there was a continuously increase, back to normal levels of oestradiol-17 beta and oestrone sulphate. The plasma levels of testosterone showed an immediate rise of brief duration after removal of the device in 5 of the boars, while in the other 6 boars the rise in testosterone levels came 4 days after removal and lasted for 3 days. In the peripubertal boars, there were no significant differences in the hormone levels between the experimental and control animals during and after scrotal insulation. However, the decrease in testosterone concentration over time, during scrotal insulation, was significant within the experimental group.     

Histochemical study of the interstitial tissue in scrotal and abdominal boar testes.

The present study describes the glycosidic content of the interstitial tissue in testes from healthy boars and from unilateral and bilateral abdominal cryptorchid boars using lectin histochemistry. The Leydig cells of healthy boars contained glycans with fucosyl, mannosyl, glucosyl, neuraminic acid and galactosyl residues, which have structural and transport functions, and participate in androgen synthesis and in cell regulation. Unilateral cryptorchidism induced high glucosyl and low galactosyl content in the Leydig cells of scrotal testes, resulting in impaired androgen production. In abdominal testes, the Leydig cells exhibited increased amounts of glucosyl and reduced amounts of galactosyl and neuraminic acid residues, resulting in defective cell regulation and lack of androgen synthesis. In healthy boars, the extracellular glycans contained fucosyl, galactosyl, glucosyl and neuraminic acid residues, which confer viscoelasticity on the interstitial tissue and participate in substrate transport, hormone binding and cell-cell interaction. Unilateral cryptorchidism did not induce anomalies in extracellular glycans in scrotal testes, but unilateral and bilateral cryptorchidism resulted in an increased content of fucosyl and galactosyl, and a decreased content of glucosyl and neuraminic acid residues in abdominal testes, leading to reduced viscoelasticity and defective substrate transport across the extracellular matrix.

Castration of the Vietnamese pot-bellied boar: 8 cases

Surgical techniques for castration of the Vietnamese pot-bellied boar and outcome are described. Vietnamese pot-bellied pig (VPBP) boars (n = 8) were admitted for castration. Data retrieved from medical records (2002–2011) for these pigs included signalment, history, reason for castration, perioperative management, surgical technique, and complications. Follow-up information was obtained from owners. A scrotal approach with closed technique was used for 6 boars with normally descended testes. A scrotal approach and open technique was used in 1 inguinal cryptorchid boar. In a hemicastrated abdominal cryptorchid boar an ipsilateral parainguinal approach was used. No complications occurred. Castration of the Vietnamese pot-bellied boar is associated with minimal complications and a satisfactory cosmetic outcome. We recommend the routine closure of the external inguinal rings, a simple and fast procedure that may prevent post-castration inguinal herniation.     

Effect of local scrotal heating on the expression of tight junction‐associated molecule Occludin in boar testes

The aim of this study was to determine whether local scrotal heating (42°C, for 1 hr) had an effect on the expression of tight junction (TJ)‐associated molecule Occludin in boar testes. Adult boars (Landrace, n = 6) were used and randomly divided into two groups (n = 3 each). Three boars were given local scrotal exposure to 42°C for approximately 1 h with a home‐made electric blanket of controlled temperature as local scrotal heating group, the other three boars received no heat treatment and were left at standard room temperature as control group. After 6 hr, all boars were castrated and the testes were harvested. qRT‐PCR, Western blotting and immunohistochemistry were used to explore the expression and localization of Occludin. qRT‐PCR and Western blotting showed that the protein and mRNA levels of Occludin significantly decreased in local scrotal heating group as compared to the control. Furthermore, immunoreactivity staining of Occludin was localized at the sites of the blood–testis barrier (BTB) and formed an almost consecutive and strong immunoreactivity strand in the control, while Occludin was limited to Sertoli cells (SCs) and no obvious immunoreactivity strand was present in local scrotal heating group. These data indicated that local scrotal heating decreased the expression of TJ‐associated molecule Occludin, which may be involved in heat‐induced spermatogenesis damage.     

Sites of virus replication in the genital organs of boars inoculated in the cavum vaginale with pseudorabies virus

To determine the sites of replication and the evolution of pseudorabies virus infection in boar genital organs, 5 Belgian Landrace boars were inoculated with pseudorabies virus unilaterally in the cavum vaginale of the testis. Virus replication took place only in cells of the tunica vaginalis of both cava vaginalia. Infection of the serosa led to exudative periorchitis and increased scrotal fluid, resulting in a severely swollen scrotal region. These experimental findings were similar to findings in boars with naturally acquired pseudorabies virus infection. Scrotal fluid contained large amounts of virus, making it a useful specimen for diagnosis of the disease in affected boars.     

Surgical treatment for different forms of hernias in sheep and goats

Sheep and goats are frequently presented with different forms of hernias to veterinary clinics. The aim of this study is to investigate the outcome of the surgical treatment of abdominal, umbilical, inguinal and scrotal hernias in sheep and goats. Fifty-eight clinical cases (sheep = 44, goat = 14) were presented to the Veterinary Teaching Hospital, College of Agriculture and Veterinary Medicine, Qassim University, Saudi Arabia from September, 2003 to September, 2006. These animals had abdominal (sheep = 30, goat = 10), umbilical (sheep = 6, goat = 4), inguinal (sheep = 7) and scrotal (sheep = 1) hernias. All the cases of hernias in sheep and goats were subjected to full study including the history of the case, classification of hernias, the size of the hernial ring, surgical repair of the hernias, adhesions between the hernial sacs in each case, the postoperative care and follow up of the cases. The results revealed that gender had an effect on the incidence of hernia. The incidence of abdominal hernias was higher in females and the incidence of inguinal hernia was higher in males. There was a positive correlation between the history of hernia and the degree of adhesion. For the sheep, 26 out of 30 cases of abdominal hernia had good outcomes and the healing was excellent. There were postoperative complications in 4 ewes. For the goats, there were slight swellings at the site of operation in 2 out of 10 cases of abdominal hernia, while the remaining 8 cases had good outcomes. There was one case of umbilical hernia with an umbilical abscess that had broken down with sepsis formation at the surgical site. In conclusion, the success rates of surgical treatment for all types of hernias were very high and there were no significant differences in the success rates among the different types of hernias in both sheep and goats. The types of suture materials and the types of hernias had no significant effect on the outcome of the surgical treatment.

Electroejaculation and artificial insemination in Vietnamese potbellied miniature pigs

A 15-month-old Vietnamese miniature boar was examined because of suspected infertility. A breeding soundness examination was conducted, using electroejaculation under anesthesia for semen collection. Semen values were normal despite a subpubic location of the testes. Artificial insemination of a gilt with extended semen resulted in the birth of a litter 111 days later. Vietnamese potbellied boars have small and sometimes nearly undetectable scrotal pouches, which may cause the producer to question the fertility of the boars.     

Excretion of porcine parvovirus through the genital tract of boars

The putative binding of porcine parvovirus (PPV) to semen components in vitro was examined along with the shedding pattern of PPV in oronasally infected boars. Porcine parvovirus DNA was determined to be bound to spermatozoa that had been incubated in vitro with PPV and washed to remove loosely adherent virus. To determine whether PPV was shed in the semen, four 8-month-old boars, seronegative for PPV, were inoculated oronasally with a virulent strain of PPV. Prior to virus inoculation, a catheter was surgically implanted in the vas deferens for the purpose of collecting cauda epididymal semen free of extrinsic contamination. Epididymal semen specimens were collected prior to inoculation and daily thereafter for 21 days. A fifth boar was inoculated oronasally with PPV, but semen was collected by electroejaculation twice weekly for an equal period of time. Reproductive glands and semen specimens from all boars were examined by nucleic acid hybridization for the presence of viral DNA. All boars seroconverted to PPV, as evidenced by serum antibody titers ranging from 512 to 8,192 hemagglutinating inhibition units/50 microliters. Porcine parvovirus DNA was detected in epididymal semen of 3 of 4 catheterized boars on postinoculation days 5 through 9, but not in semen obtained by electroejaculation. Viral DNA was consistently detected in tissue samples collected on postinoculation days 8 and 21 from the scrotal lymph nodes (4 of 5 boars) and epididymides (3 of 5 boars).
