5. Cephalosporins:- A group of antibiotics derived from a fungus that have a wide range of activity against many important bacteria and are useful for treatment of serious infections. The historic classification of Cephalosporins is by generations.
Exs:- 1. Cefaclor (Ceclor)
2. Cephalothin (Keflin)
3. Cephradine (Anspor)
6. Erythromycins and like drugs:- An antibiotic that binds to ribosomal subunits of bacteria and suppress protein synthesis, used in treatment of respiratory infections, and in infections where patient is sensitive to penicillin.
Exs:- 1. Azithramycin
2. Clarithromycin
7. Pencillins:- An antibiotic of beta ring structure produced by the molds pencillium notatum and penicillium chrysogenum. It is bactericidal killing bacteria by interfering with their cell wall synthesis. It acts on both organisms. Pencillinase is capable of inactivating the pencillin. Hypersensitivity forms the most important adverse reaction.
Exs:- 1. Amoxicillin (Amoxin)
2. Ampicillin (Omnipen)
3. Penicillin V potassium (Pen-Vee)
8. Tetracyclines:- An antibiotic which acts against most pathogenic bacteria, rickettsias, chlamydias and mycoplasma.
Exs:- 1. Doxycycline
2. Tetracycline

HUMAN BONE STRUCTURE - LESSON 200

-
Now in this post we will learn about the structure of the bone. In our human body there are 206 bones of different types are there.

These bones are mostly present in the limbs, including those of the fingers and toes are long bones. Except the wrist, ankle, and kneecap these long bones are located in most. 2.
