Abstract

Penyakit tulang belakang atau biasa disebut nyeri punggung bawah dapat terjadi pada orang dewasa yang lebih tua yang dapat mengubah anatomi nukleus pulposus (NP) dan menyebabkan degenerasi diskus intervertebralis. Baru-baru ini solusi alternatif telah dikembangkan injectable biomaterial pada operasi pasca-mikrodisektomi sebagai material pengganti NP. Penelitian ini membahas terkait studi pengaruh penambahan chitosan pada silicone rubber terhadap sifat fisik dan mekanik sebagai kandidat injectable material untuk pengganti NP. Penambahan chitosan yang digunakan sebesar sebesar 10,20,30,40, dan 50% volum dari total silicone rubber/chitosan. Sampel kemudian dilakukan pengujian FTIR, XRD, curing time, injectable performance, water content dan kekuatan tarik. Penambahan 10%chitosan memiliki nilai curing time paling cepat selama 63.30 ± 1.50 menit Sedangkan untuk water content, kandungan air terbanyak pada penambahan 50%chitosan dengan 16.71±1.41%. Seluruh sampel menunjukkan kemampuan yang baik dalam mengisi rongga-rongga cetakan saat diinjeksikan serta mampu mempertahankan bentuknya ketika berada didalam lingkungan ph7. Dalam hal pengaruhnya terhadap sifat mekanik, penambahan chitosan relatif menurunkan nilai kuat tarik.

Abstract

Sectoral economic growth affects the level of poverty in the area. High economic growth does not merely reduce poverty. Equitable distribution of income is also a matter that needs to be considered in line with increased economic growth. High economic growth is the process of accumulation of sectoral economic growth that has undergone a structural shift in its journey. Changes in economic structure are marked by a decrease in the contribution of the agricultural sector and an increase in the contribution of the industrial sector, both in gross domestic product (GDP) and in employment. Economic growth needs to be directed towards economic sectors that are effective in reducing poverty and creating equitable distribution of income. The purpose of this study is to answer the question of how the influence of sectoral economic growth on poverty in East Java. For this purpose the panel data regression model is used. The selection of variables is based on research objectives. Agriculture sector GRDP (VP), industrial sector GRDP (VI) and service sector GRDP (VJ) represent sectoral economic growth. The results of the test show an increase in the contribution of the industrial sector effectively reduces poverty. In other words, between the agriculture, industry and services sectors, only the industrial sector has positive and significant parameters for poverty in East Java.

Abstract

Fertility is an important indicator for the success of state development, especially in the health sector. It can be estimated through direct and indirect methods. This study aimed to determine the fertility rate in East Java province indirectly using the Palmore Formula. This study was a descriptive analysis using secondary data from the 2015 Inter-census Population Survey / Survei Penduduk Antar Sensus (SUPAS). It calculated the rate directly and manually. The Total Fertility Rate (TFR) was at 2.02 per two children born by each mother in East Java province. It was compared with the national average published by the Central Bureau of Statistics within 5 periods of SP1990, SUPAS 1995, SP2000, SUPAS 2005, and SP2010. In each period, the rate was lower without any difference. The Palmore Formula is considered a good method for estimating fertility rates.

Abstract

BACKGROUND: Immunoglobulin-G (IgG) is a product of the initial response to secondary immune response, which accumulates in distal segment of the nerve after crush injury. Thymoquinone modulates the adaptive immune response. Effect of thymoquinone administration on local IgG levels of Rattus norvegicus Wistar rats sciatic nerve crush injury model has not been elucidated.METHODS: This was an experimental study, with 63 Rattus norvegicus Wistar rats that divided into 9 groups. Three groups were given placebo, 3 groups were given 100 mg/kg/day thymoquinone, and 3 groups were given 250 mg/kg/day thymoquinone. The rats were terminated based on the assigned group at 5x24, 6x24, and 7x24 hours and then the IgG levels were measured using sandwich enzyme-linked immunosorbent assay (ELISA).RESULTS: There was a significant difference in IgG levels after administration of 100 and 250 mg/kg/day thymoquinone at 5x24 hours and 7x24 hours post-injury compared to the rats that were given no treatment. A significant difference of IgG levels was also found after administration of 100 mg/kg/day thymoquinone group at 6x24 hours post-injury. Critical point of decreasing local IgG of all groups happened at 6x24 hours after injury, however, there was no significant difference in the median levels of thymoquinone at doses of 100 mg/kg and 250 mg/kg.CONCLUSION: Local IgG levels in distal segment of the sciatic nerve crush injury is lower in rats that were given 100 mg/kg thymoquinone treatment compared to the rats that receive no thymoquinone treatment since 5x24 hours after injury. Thymoquione administration should be given immediately after the crush injury until before 6x24 hours post-injury to decrease antibodies in degeneration process.KEYWORDS: thymoquinone, immunoglobulin-G, crush injury, sciatic nerve

Abstract

Ossification of ligamentum flavum (OLF) is calcification of the ligamentum flavum, which might narrow the spinal canal and causes myeloradiculopathy. This condition mainly affects the lower thoracal segment. Published reports on OLF are mostly from East Asia. There was only one Indonesian OLF case that had been published. The majority of OLF involves a single level only. This is the first Indonesian case-report on multilevel OLF. Through this case report, we aim to describe the natural history of the patient and our treatment strategy in managing the multilevel OLF case. Delayed time to surgery is the key contributory factor in unfavorable surgical outcome in thoracic OLF. Choosing an appropriate surgical procedure is important. The neurological symptoms of the patient may not improve or worsen when an inadequate surgical procedure is used.

Abstract

The intramedullary spinal cord cavernoma is a rare vascular disease that occur within spinal cord or intramedullary and account for about 5%-12% of all pathology in the spinal vascular disease. We report a clinical progression of disease and evolution of the haemorrhage every years until patient underwent surgical procedure. A 63-years old male with progressive weakness of the lower extremity since 1 month before admission, worse in the left side He also complained loss of sensation at the level of the T4 and below it. Patient suffer three times rebleeding before underwent surgery. MR imaging showing intramedullary spinal cord cavernoma and a histology examination exhibited the characteristics of a cavernoma. Intramedullary spinal cord cavernoma is a rare disease that should be treated before rebleeding occur and enlargement of the lesion. Postoperative neurological function in intramedullary spinal cord cavernoma patient is determined by the preoperative neurological status.

Abstract

Tumour excision and laminoplasty are commonly performed as surgical treatment of extra vertebral extension of cervical schwannoma. It is worth knowing that the conventional technique of multilevel laminectomy may hinder younger patients in the long-term. This article reports a 30-year old man with an intradural-extramedullary tumour which extended from C4 to T1 that underwent modified laminoplasty. This modified technique is preferable in maintaining the anteroposterior diameter of spinal canal as well as reducing the displacement of guttered laminae
