Abstract

Background: Bisphosphonates, such as alendronate (ALE), have been known to be effective in the treatment of bone cancer and osteoporosis. However, it has been reported that the systemic administration of ALE causes a considerable side effect. Thus, the formulation injectable bone substitute (IBS) for local administration of ALE, which functions as drug delivery system (DDS) as well as filling agent in osteoporosis-induced bone fracture, is needed. Objective: To establish the biodegradable and biocompatible formulation for ALE in injectable form which supports the drug delivery system and acts as filling agent in bone fracture. Methods: Hydroxyapatite (HA) was added to the mixture of gelatin and hydroxypropyl methyl cellulose (GEL-HPMC). ALE was added to the mixture and semisolid form was prepared for granulation. The dried granule, as injectable matrix, was grinded and mixed with appropriate amount of Na2HPO4. Results: Porosity of injectable form was higher than those of granule form. Injectable semisolid form was produced by adding 0.8 mL Na2HPO4 on each gram of granule with 10-12 min setting time. MTT assay showed that matrix was biocompatible showed by more than 100% viability. In vitro dissolution study showed that ALE was slowly released in more than 20 days. Conclusions: The formula of IBS using HA-GEL-HPMC may act as an effective drug delivery system for local administration of ALE in bone fracture.

Abstract

Background: Meningitis defined as an inflammation of the meninges, a membrane that surrounds the brain. The inflammation is a result from bacterial infection. Central nervous system infection is a medical emergency because of the progressivity and potentially life-threatening. Antibiotics usage become crucial to reduce morbidity and mortality. Objective: This study was aimed to assess the use of antibiotics, prescribed for patients with bacterial meningitis in Neurology Department of Dr. Soetomo General Hospital Surabaya from January 2010 until June 2015. Methods: Retrospective study using medical record of inpatients obtained from January 1st 2010 until June 30th 2015. The inclusion criteria were inpatients with bacterial meningitis (diagnosed by physician using CT scan data, lumbal puncture and clinical signs and symptoms) and prescribed with antibiotics. Patients with antibiotics therapy less than 3 days and infection other than bacterials were excluded. Results: From 85 patients, male to female ratio was 1.66. Meningitis appear to be mostly occured in productive age, 39 (45.88%) in 15 - 29 years old and 40 (47.06%) in 30 - 60 years old. Number of antibiotics prescribed were 130 prescriptions, as single and combination therapy. The most prescribed antibiotic was cephalosporins (97 prescriptions), dominated by 2 g twice daily ceftriaxone with 86 (66.15%) from overall prescriptions. Followed by metronidazole and fluoroquinolons,11 (8.46%) and 8 (6.15%) respectively. In addition, there were 26 prescriptions of combination therapy, mostly ceftriaxone and metronidazole. Conclusion: Bacterial meningitis are mostly treated using ceftriaxone which is an appropriate drug of choice.

Abstract

Background: CIPN (Chemotherapy-induced Peripheral Neuropathy) primarily affects the sensory system and is accompanied by pain, autonomic dysfunction, and motor impairments. Alterations of intracellular second messengers at the supraspinal level in CIPN needed to be explored more. In addition, there is a lack of evidence regarding implications for the supraspinal area through the propagation of pain via the ascending pathway. Objective: In this study, we evaluated the effect of fenofibrate as a PPARα agonist in suppressing the development of CIPN. Methods: Twenty-four mice were distributed to the normal control group, neuropathy group, and neuropathy with the treatment of fenofibrate 75 and 150 mg/kg groups, resulting in 6 animals per group. Oxaliplatin was injected on days 0, 2, 4, and 6. The hot plate test was performed before the oxaliplatin administration and then continued on the 7th, 14th, and 21st days. Thalamus tissues were collected to measure the TRPA1 mRNA expression using qPCR. Results: Fenofibrate 75 mg/kg co-treatment with oxaliplatin tended to prevent the enhancement of oxaliplatin-induced thermal hyperalgesia in hind-paw withdrawal and rubbing responses. Furthermore, fenofibrate 75 and 150 mg/kg co-treatment with oxaliplatin significantly reduced the relative TRPA1 mRNA expression but did not modulate the relative BDNF mRNA expression in the thalamus. Conclusion: PPARα agonist has a potential effect in suppressing the development of CIPN. However, given the various perspectives on the role of neurotrophins in CIPN, additional non-clinical investigations, are needed to provide more insight into other mechanisms of CIPN and the role of PPAR agonists.
