Abstract

World Health Organization (WHO) in 2005 reported that cases of tuberculosis (TB) in the world occur more than 8 million annually and 5-10% were attacked in spine. The most effective treatment of spinal TB is evacuation of infected bone segments and fill with bone graft. It has been synthesized and characterized of injectable bone substitute (IBS) paste based on hydroxyapatite, gelatin and streptomycin. IBS paste synthesized by mixing hydroxyapatite and gelatin 20% w/v with 75:25, 70:30, 65:35 and 60:40 ratio and streptomycin 10 wt%. The mixture was then added with hydroxypropyl methylcellulose (HPMC) 4% w/v as suspending agent. In vitro characterization performed include acidity (pH), injectability test, setting time, cytotoxicity (MTT assay) and microbacterium test. Acidity test results indicate a fourth variation of the samples had pH values approaching normal body pH (7,3 to 7,6) and is able to maintain stability when measured in 7 days. Injectability test results indicate IBS paste is injectable with the highest percentage of the injectability value at 97,74% ± 0,19%. IBS paste has been setting within 30 minutes to 1 hour when injected on hydroxyapatite scaffold that resembles the bone cavity and is able to cover the pore scaffold seen from the Scanning Electron Microscope (SEM). Scaffold pore size is smaller from range of 780,8 to 835,4 μm into 225,2 μm. MTT assay results showed that IBS paste is not toxic and experiencing proliferation (viability >100%) that are expected to trigger osteoblast cell growth when applied. Microbacterium test results showed that IBS paste is an antibacterial seen from inhibition zone diameter of Staphylococcus aureus and has a high strength-sensitive antibacterial. Thus, hydroxyapatite, gelatin and streptomycin composites had qualified as injectable bone substitute which applied in cases of spinal tuberculosis.

Abstract

Indonesian Health Ministry  Data showed that 5.3% of 100,000 population in Indonesia suffer from corneal ulcers. Corneal ulcer is one of the five leading causes of largest blindness  morbidity and loss of vision. Corneal transplant being the only medicine accepted widely despite there are many post-surgery complications. The study was conducted to review the initials make a synthetic cornea from natural ingredients collagen type I composite with a glikopolimer from poly (1,8-octanediol-co-citrate) (POC) and poly (vynyl-alcohol) (PVA) hydrogels form to review increase the strength of mechanical and biodegradibilty as candidate synthetic cornea. The result of Fourier Transform Infra Red (FTIR) tin that strong cross Occurs on Force C = O stretching Which is a cluster formation of ester IN 1735 cm-1. The result of tensile test showed that the value of elasticity modulus tends to decrease with increasing concentration of collagen with modulus of elasticity in a row for a review variation collagen 1%, 3%, and 5% is 13.26 MPa, 13.21 MPa, and 11.5 MPa. Moisture balance test results Phosphate Buffer Saline (PBS) for 7 days for a review sample of collagen Variation 1%, 3%, and 5% is 89%, 91% and 92%. Spectroscopic test results showed that all the various samples can continue light until appoximately 98% accordance to standart of cornea. The synthetic cornea from collagen type 1 and glycopolymer from poly(1,8-octanediol-co-citrate) (POC) and poly(vynyl alcohol) (PVA) have a potential to be solution for irreversible blindness caused by corneal ulcers.

Abstract

In Indonesia, the traffic accident causing 6 million people suffered injuries, particularly injuries fractures. 46.2% incidence of fractures occur in the lower extremities, 25% of them dying, 45% had a physical disability, 15% experienced psychological pressure and only 10% were healed well. Implant (graft) are used to support and accelerate the healing process of broken bones (bone healing). This study was done to make microbial cellulose-hydroxyapatite scaffold as a candidate for bone healing. Microbial cellulose obtained from culturing Acetobacter xylinum is used as a matrix and hydroxyapatite as a filler that is synthesized using the method of immersion in a solution of CaCl2 and KH2PO4, to increase the formation of apatite crystals, added polyvinyl Pyrrolidine (PVP). Scaffold synthesized using methods of freeze dried. Formation of composites varied in the concentration of Ca2+ and PO 3- of 25:125; 50:100; 75:75; 100:50 mM. The samples were then characterized using FTIR spectroscopy which shows the phosphate groups and the carbonate indicates the formation of hydroxyapatite in the eighth sample. Furthermore, to determine the morphology and identify the elements in the scaffold used SEM-EDAX, it was found that the pore formed measuring about 150-300 μm and obtained ratio of Ca / P best on microbial cellulose scaffold-PVP-hydroxyapatite with a variation of the concentration of Ca2+ and PO43- of 100 : 50 mM is equal to 0.6046 with an average degradation rate of 18.617% and the percentage of porosity contained in the sample amounted to 88.4%. This proves that microbial cellulose scaffold-PVP-hydroxyapatite with a variation of the concentration of Ca2+ and PO43- of 100:50 mM potential as a candidate for bone healing.

Abstract

Scaring in acne remains a common problem and became therapeutic challenges for the clinician. Several modalities were introduced, and combination therapies are required to achieve satisfactory results. Skin needling and subcision reported as effective methods for treating acne scar. The skin needling technique involves puncturing the skin multiple times with a small needle to induce collagen growth, while subcision worked by tunneling the connective tissue and scattered the fibrosis scar. Platelet-rich plasma (PRP) influences wound-healing by stimulating an intense inflammatory response and growth factors, these increase in the production of extracellular matrix and granulation tissue occurs, with vascular in-growth, fibroblastic proliferation, and collagen production also accelerated. Three male patients enrolled in the study, with grades 2-3 acne scar. There are three different methods of treatment were used to see the effect of the treatment. The first patient used the combination of topical PRP and skin needling, and the second patient received a combination of PRP injection and subcision, while the third patient obtains combination between topical PRP and skin needling continued with PRP injection and subcision. Our study revealed that PRP and skin needling or subcision is a simple technique and has the potential for improvement of acne scars. Three weeks after treatment, all three patient had smoother facial skin and reduction of acne scar severity. The combination of PRP and skin needling or and subcision is a simple, safe and rapid method for acne scars treatment.

Abstract

Hematopoietic stem cells (HSCs) usage has numerous potential benefits for basic and clinical research.  Growing interest in this field is caused by possible HSCs application   to cure   various   hematologic   diseases, malignancies, immunodeficiency diseases, and inborn errors of metabolism.  Although the demand of HSCs is increasing, ex vivo culture of HSCs has various medium compositions. This article focuses on HSCs’ culture medium optimation in different medium supplements, which might overcome non-optimal HSCs culture results. Literature searching was conducted in PubMed and google scholar database. Paper selection processes were done by author separately and studies which met the eligible criteria were included in this review. A total of 53 relevant articles were identified and 11 articles that met the eligible criteria were included in this review. There are two main types of supplement, cytokines and non-cytokines.  In cytokines addition, 7 studies generally show that the supplement support HSCs expansion.  The addition of non-cytokines supplements has more diverse   result in studies.   Positive   results   with various   effectivity   in CD34+ expansion were shown in 3 studies, while one study shows a negative result. Medium supplementation must be explored more to find best substances which can optimize   HSCs   culture.   Further   research   using   non-cytokines   substance   shall   be conducted regarding its various effect and might give us a big opportunity to find an optimal condition for HSCs culture.
