We report modifications to immunocytochemical detection procedures for proliferating cell nuclear antigen (PCNA) which permit its identification in liver samples previously fixed for BrdU immunocytochemistry. Both methods have been used for the assessment of phenobarbital-induced cell proliferation in rat liver. The difficulties associated with the hitherto unsuccessful application of PCNA immunocytochemical methods to tissues fixed in formalin for BrdU visualization were overcome by epitope unmasking with acid hydrolysis, extension of primary antiserum (PC10) incubation, and employment of streptavidin-ABC-HRP. BrdU delivery via osmotic minipumps for 48 hr before euthanasia, followed by fixation in cold formalin for 14 days, yielded reliable and reproducible hepatocellular labeling and a peak of cell proliferation in all lobes on Day 3 (i.e., labeling during Days 1-3) of dosing with 80 mg/kg/day phenobarbital. Labeling indices (LI) of both control and phenobarbital-treated liver were lower in the left and right median lobes as compared with the lateral lobes. In sections of the left lateral lobe from the same liver, PCNA immunocytochemistry revealed a peak of proliferative activity (about one third of the maximum LI generated by BrdU incorporation) on Day 1. These findings, together with the advantages and disadvantages of both techniques, are discussed in the context of their applications to different investigative requirements.

Abstract Thoracoschisis is an extremely rare congenital anomaly associated with limb body wall defect and diaphragmatic hernia. We describe a case of a female infant who was noted at birth to have tissue coming through a left sided thoracic defect next to an accessory nipple. The stomach bubble was displaced superiorly on radiographs. At surgery the tissue was attached to the left lateral lobe of the liver and was protruding through the chest wall via an intercostal defect below an eventrated diaphragm. The tissue was resected and the defect closed. Pathological examination was consistent with a mesenchymal hamartoma. The diaphragm may have formed abnormally in this case due to the presence of the mesenchymal hamartoma in this location.

Abstract Background The use of surgical metal clips is crucial for ligating vessels in various operations. The currently available metal clips have several drawbacks; they are permanent and interfere with imaging techniques such as computed tomography (CT) or magnetic resonance (MR) imaging and carry the potential risk of endo-clip migration. We recently developed a novel magnesium (Mg) alloy for biodegradable clips that reduces artifacts on CT imaging. This study aimed to examine the tolerance, biodegradability, and biocompatibility of the Mg alloy clips compared with those of standard titanium (Ti) clips in hepatectomy. Methods Thirty Wistar rats were divided into two groups based on the clip used (groups A and B). The vascular pedicle, including hepatic artery, portal vein, bile duct, and hepatic vein of the left lateral lobe, was ligated with the Ti clip in group A or the Mg alloy clip in group B, and then the left lateral lobe was removed. The rats were sacrificed at 1, 4, 12, 24, and 36 weeks after surgery. Clinical and histological evaluations were performed. Absorption rate was calculated by measuring the clip volume. Results Although the Mg alloy clips showed biodegradability over time, there were no significant differences in the serum concentration of Mg between the two groups. The remaining volume ratio of Mg alloy clips was 95.5, 94.3, 80.0, 36.2, and 16.7% at 1, 4, 12, 24, and 36 weeks, respectively. No side effects occurred. Most of the microscopic changes were similar in both groups. Conclusions The new biodegradable Mg alloy clips are safe and feasible in vessel ligation for hepatectomy in a rat model and reduce artifacts in CT imaging compared with the standard Ti clips.
