Ultrasonography is a safe, rapid, and non-invasive diagnostic tool that has been previously used for imaging infants and canine neonatal brains. The purpose of the present study was to describe the ultrasonographic appearance of the brain in clinically normal caprine neonates. Ultrasonographic examination was done on 12 day-old goat kids, transverse and sagittal transcranial scans were obtained through the frontal bone. Three image planes were recorded through transverse scans including plane I (level of the caudate nucleus), plane II (level of the rostral diencephalon) and plane III (level of the caudal diencephalon). Parallel post mortem examinations were done for two kids that died a day following examination due to accidental trauma by the dam. Reliable and repeatable ultrasonographic images of the goat kid’s brain were described based on the gross post mortem findings. The head of the caudate nucleus was taken as an anatomical landmark in the plane I where it appeared as a curved hyperechoic structure. In plane II, the longitudinal fissure with its characteristic umbrella-like structure was taken as a landmark, while in plane III, the laterally located hyperechoic hippocampus was taken as a landmark. Normal ultrasonographic examination of the caprine neonatal brain represented the basis for diagnosing congenital brain lesions as well as intracranial hemorrhage.

This study was performed to evaluate the role of electroacupuncture on kidney 1 (Ki1) acupoint to prevent the heart and brain injury following ischemia/reperfusion of both kidneys. 24 Sprague Dawley rats were randomly assigned into four equal groups. In the treatment 1 group, following anesthesia, acupuncture needles were inserted on Ki1 on the palm of both hindlimbs and connected to electroacupuncture unit for a 3.00 Hz direct current, 1 hr before surgery until the end of surgery. In treatment two groups, the electroacupuncture was also performed 48 and 24 hr before the operation, with the same protocol as treatment 1. Control 1 and control 2 groups had the same procedures like the treatment ones, except for acupuncture. Immediately after reperfusion, the samples of brains and hearts were taken and prepared for microscopic examination. Histopathological study of the heart in the control and treatment groups showed the breakage of myofibrils, hyaline necrosis, edema and disorganization of myocytes. The severity of cardiac lesions was decreased in both treatment groups in comparison with the controls. Brain in control and treatment groups showed ischemic necrosis, disorganization of the neurons in the hippocampus, and edema. The severity of lesions was reduced in the treatment groups and showed a significant difference between the control and treatment 1. It could be concluded that electroacupuncture on the Ki1 point could reduce the severity of damages induced by renal ischemia/reperfusion in the remote organs of the heart and brain.
