Purpose: Fractures of the posterior column and posterior wall acetabulum are the most common pelvic fractures. In this study, we aimed to test the design of a new acetabular plate that combines the spring plate’s function and the plate’s reconstruction. This design should ease fixation and reduce surgery time, but is biomechanically untested. We analyzed this plate using finite element analysis (FEA). Materials and Methods: This observational study compares seven pelvic models: normal pelvis, posterior wall acetabular fracture, posterior column fracture, these two fractures combined, and the three fracture models fixed with the new acetabular plate. The evaluation was based on the analysis of deformation and stress distribution in each pelvic model under a force of 1,000 N directed at 45° from the sagittal and coronal planes. Results: In the normal pelvis, the greatest deformity was found on the ischial tuberosity (up to 3.91 mm and stress distribution tend to be homogenous. The new acetabular plate normalized the deformity and stress distribution to resemble the normal pelvis with highest stress on the ischial tuberosity and inferior side of the acetabulum. The largest deformation was in the middle of the plate and in the screw. Conclusion The novel plate can normalize stress and deformity in a fractured pelvis and may provide a solution for combining the posterior column and posterior wall of the acetabulum.

A cruciate ligament avulsion is a much less common form of injury than a cruciate ligament tear. Simultaneous tibial avulsion fractures of both cruciate ligaments occur even more rarely. Over the last decades, many studies have described arthroscopic fixation of acute cruciate tibial avulsion fractures, but arthroscopic treatment in a late presenting patient has not been reported in the literature. This case report presents a 32-year-old female with a chronic tibial avulsion fracture of both anterior cruciate ligament and posterior cruciate ligament. Simultaneous fixation of both fractures was performed arthroscopically at week four post-injury. At one year of follow-up, the patient had demonstrated full knee range of motion and stable knee with no complaints, and achieved excellent clinical outcomes. Radiographs showed union of both fractures, and the patient had resumed high-impact exercises.

Heterotopic ossification (HO) is the growth of bone in soft tissue, and can be broadly classified into neurogenic, genetic and traumatic causes. The pathophysiology of HO remains unknown. This disorder is extremely rare in infants and can mimic or coexist with thrombophlebitis, cellulitis or osteomyelitis. Most importantly, HO has to be differentiated from bone-forming tumours such as osteosarcoma and osteochondroma. We report a case of traumatic HO in a fiveday- old newborn following intravenous cannulation of the right wrist and left ankle, with the latter complicated with osteomyelitis. We highlight the clinical and radiological features of HO and differential diagnoses of soft tissue ossification in early childhood.

We evaluated the safety of fucoidan from Gagome Kombu (GKF) in genotoxicity tests. In bacterial reverse mutation test, GKF had no reverse mutation inducing activity on five bacterial strains with or without S9 metabolic activation. In chromosome aberration test, GKF had neither structural nor numerical chromosome aberration inducibility with or without S9 metabolic activation. In micronucleus test, neither formation of micronuclei nor decrease of mironucleated reticulocytes was observed in the bone marrow of the mice treated by GKF. These results indicate that GKF has no genotoxic activities under the condition of this study.

Coix lacryma-jobi L. var.ma-yuen Stapf (Coix seed) is a grass crop that has long been used in traditional medicine as a nourishing food. However, high-intake safety of the extract of the husks, pellicles and astringent skin of Coix seed has rarely been evaluated. We performed a safety test of hot water extract of all parts of Coix seed (CRD extract) in rats. CRD extract showed no significant toxicity on body weight, blood analyses, urinalysis and histopathological examination in acute toxicity tests.

Fresh kiwi fruit freeze-dried juice has been traditionally used for constipation of elderly patients. Its effectiveness and safety was studied in 42 elderly patients (age 60–84: median age 67±6) suffering from mild to moderate constipation, taken as a food supplement of 6 capsules/3 times per day for 4 weeks following a one week control period, after receiving written informed consent. Bowel habits and generic quality of life questionnaires were monitored. Bowel habits such as evacuation time and stool quality improved from the 14^th day and continued for 28 days compared to the control period.
Quality of life in terms of external appearance (such as skin and edema), lumbago, and headache improved. In conclusion, freeze-dried fresh kiwi fruit juice had a laxative and QOL-improving effect on the elderly. No apparent adverse effects were observed.

Coix lacryma-jobi L. var.ma-yuen Stapf (coix seed) is a grass crop that has long been used in traditional medicine as a nourishing food. However, high-intake safety of the extract of the husks, pellicles and astringent skin of coix seed has rarely been evaluated. We performed a 28-day repeated dose oral toxicity test of hot water extract of all parts of Coix seed in rats. The extract showed no significant toxicity on body weight, blood analyses, urinalysis and histopathological examination in acute toxicity tests.

Coix lacryma-jobi L. var. ma-yuen Stapf is a grass long been used in traditional medicine as a nourishing food and reported to possess pharmacological effects including anti-tumor, anti-obesity, anti-diabetic, etc. In order to evaluate the possible mutagenicity of the hot water extract of all parts (husks, pellicles, and astringent skin) of the food, we performed a reverse mutation test in bacteria, a mouse lymphoma assay and a mouse micronucleus test. The results of all tests were negative. It was concluded that the extract has no mutagenicity for living bodies.
