Background: Tendons are dense connective tissues composed primarily of a highly
organized type I collagen extracellular matrix (ECM). Which enables a tendon to perform its
mechanical function of force transfer. Platelet rich plasma (PRP) serves as a growth factor
agonist and has both mitogenic and chemotactic properties.
Aim: investigation the effect of PRP in tendon healing in rats, and evaluation the rate of
possible complications.
Materials and Methods: The study included (35) rats, (5) rats only used as donors for PRP,
while (30) rats separated as PRP group:(1); injection, group (2); spray, group (3); mixed.
The left leg in all rats (control group) receives nothing, while the right leg receives PRP as
separated groups. Each rat was kept in a separated cage and checked on until the end of the
follow up period (15-30) day. After (15) and (30) days post-treatment, (5) rats of each group
were sacrificed, and their Achilles tendons were extracted and examined histopathologically.
Stained sections examined for the number of the inflammatory cells / HPF,
the ratio between collagen 1 and collagen 3 and the arrangement of the collagen fibers

Background of the Study: Bacterial and Viral infections are often hard to be distinguished in daily clinical practice. Biological markers obtained from a routine examination play an important role to minimize time in providing diagnose and giving therapy. Recently, the use of Neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) is greatly considered to differentiate types of infection found in the patients presenting with fever.
Method: This study uses prospective cohort study design and involves patients presenting with fever who are admitted to the ICU. The initial NLR, MLR, and PLR is examined and categorized into types of infection found. The ANOVA test and t-test are performed to find out the difference among study groups with the value of α = 0,05.
Result : This study involves 207 patients (92 male patients [44%]) presenting with fever with the average age of 45,6 ± 14,6 years old. The majority of cases (135 cases [66,5%]) in patients with fever results from bacterial infection; The study also finds 47 cases (34,8%) of typhoid fever and 30 cases (22,2%) of pulmonary tuberculosis. Dengue hemorrhagic fever (DHF) is the most commonly found viral infection with 52 cases (76,4%). The significant diagnose of bacterial infection shows higher value of NLR and MLR than that of viral infection (P < 0,001); Urinary tract infection has the highest value of NLR and MLR, amounting to 9,4 ± 3,6 and 0,23 ± 0,20, respectively. In general, the value of PLR is lower than that of viral infection (P < 0,001).
Conclusion: Neutrophil-lymphocyte ratio, MLR and PLR have benefit to predict diagnosis for the patients presenting with a fever. Bacterial infection is associated with the high value of NLR and MLR, and PLR generally has a lower value in viral infection cases.
