Perforating wounds were made on the cranial surface of 32 teats in eight dairy cattle. The teats were distributed into eight groups with four kinds of suture patterns. The used suture patterns were Gambee in Groups A and E, continuous 2‐layer (Cushing for submucosal layer, continuous horizontal mattress for intermediate layer and skin) in Groups B and F, separated 2‐layer (simple continuous for mucosal layer, vertical mattress for intermediate layer and skin) in Groups C and G, and 3‐layer (simple continuous for mucosa] and intermediate layers, simple interrupted for skin) in Groups D and H. The wounds of Groups E, F, G and H were subjected to 3.64 J/cm2 dose of low‐level laser, using a helium‐neon system with an output of 8.5 mW, continuous wave at 632.8 nm. Histopathologically, healing was different between various suture patterns and between low level laser therapy (LLLT) and non‐LLLT‐groups. The results suggest that the 3‐layer pattern was the best and LLLT could accelerate healing of perforating wounds of the teat in dairy cattle.

Administering intraluminal fluid can improve the acoustic window for the visualization of the lumen and wall layers in the cavitary organs. Microbubbles in ultrasound contrast agents can also be used for intracavitary applications to enhance visualization of the lesion in human patients. However, there was no literature extending the clinical application of intraluminal contrast-enhanced ultrasonography (CEUS) to patients with naturally occurring diseases in veterinary medicine. This case series aims to describe the detailed application and diagnostic value of intraluminal CEUS in six clinical cases with naturally occurring gastrointestinal (GI) and urinary tract diseases.

This study was conducted to determine the ultrasonographic features of the liver, gallbladder, spleen, kidneys, and urinary bladder of 24 apparently healthy male and female long-tailed macaques (LTM) and the correlations of organ measurements with body weight and crown–rump length. The animals were grouped into 12 males and 12 females. Examination was performed in sedated LTM using an ultrasound machine with 6.0 MHz microconvex scanner. Ultrasound appearance, dimensions, and echotexture of the liver, gallbladder, kidneys, spleen, and urinary bladder were evaluated. The results showed that there were no sex-related differences in echo mean values, thickness, and length of the selected abdominal organs. The liver was hypoechoic to isoechoic with the right renal cortex, while spleen was isoechoic to hyperechoic to left renal cortex. Spleen was hypoechoic to isoechoic to the liver. Gallbladder and urinary bladder had hypoechoic to hyperechoic thin wall with anechoic lumen. There was a statistically significant and moderate positive correlation between the volume of the left kidney and body weight. The right kidney volume was greater than the left kidney and the total renal volume had a statistically significant and moderate positive correlation with body weight. This study established the reference values for ultrasonographic features of selected abdominal organs of rescued LTM.
