[Comparison of ilioinguinal-iliohypogastric nerve block versus spinal anesthesia techniques for single sided inguinal herniorrhaphy].

Objectives: The aim of the study is to compare the hemodynamic effects, postoperative analgesia, time to achieve discharge criteria, and patient-surgeon satisfaction of patients who are assigned for single sided inguinal hernia repair operated under iliohypogastric ilioingıinal nerve block (IHNB) or spinal anesthesia.

Methods: Twenty-five ASA I-III patients in Group S received 15 mg 0.5% hyperbaric bupivacaine intrathecally, and 25 ASA I-III patients in Group I received IHNB with 20 mL 0.

Modification of osteoarthritis in the guinea pig with pulsed low-intensity ultrasound treatment.

Objective: The Hartley guinea pig develops articular cartilage degeneration similar to that seen in idiopathic human osteoarthritis (OA). We investigated whether the application of pulsed low-intensity ultrasound (PLIUS) to the Hartley guinea pig joint would prevent or attenuate the progression of this degenerative process.

Methods: Treatment of male Hartley guinea pigs was initiated at the onset of degeneration (8 weeks of age) to assess the ability of PLIUS to prevent OA, or at a later age (12 months) to assess the degree to which PLIUS acted to attenuate the progression of established disease.

Assessment of tissue repair in full thickness chondral defects in the rabbit using magnetic resonance imaging transverse relaxation measurements.

The purpose of this study was to determine if the noninvasive and nondestructive technique of magnetic resonance imaging could be used to quantify the amount of repair tissue that fills surgically-induced chondral defects in the rabbit. Sixteen 4-mm diameter full-thickness chondral defects were created. A photopolymerizable hydrogel was used to seal the defects as a treatment modality.

Effects of knee injection on skeletal muscle metabolism and contractile force in rats.

Objective: We tested the hypothesis that intrusion of the knee joint capsule alters quadriceps muscle metabolism and function independently from the damage induced to knee cartilage.

Methods: Adult rats were separated into four groups: intraarticular injections of saline (SAL; n=9); intraarticular injections of papain, a model for osteoarthritis (PIA; n=7); sham injections (SHAM; n=8); and controls (CTL; n=5). 31P magnetic resonance spectroscopy (31P-MRS) was performed after 2 weeks.
