To maintain the desired SAL at the plant is task which demands great care and control over Man, Machine & Method. This summarize work will definitely help you as hand note.
It is process of “Establishing documentary evidence that provide a high degree of assurance that a specific process will consistently produce a product meeting its predetermined specifications and quality attributes”.
In the pharmaceutical industry, it is very important that in addition to final testing and compliance of products, it is also assured that the process will consistently produce the expected results.
Validation is action of proving in accordance with the principles of good manufacturing practices, that any procedure, process, equipment, material, activity or system actually leads to expected results.
Cleaning validation is documented evidence with a high degree assurance that one can consistently clean a system or a piece of equipment to predetermined and acceptable limits.
The primary regulatory concern driving the need for cleaning validation is cross contamination of the desired drug substance either by other API from previous batch runs or by residues from the cleaning agents used.
The prime purpose of validating a cleaning process is to ensure compliance with federal and other standard regulations
1. Cross contamination with active ingredients
Contamination of one batch of product with significant levels of residual active ingredients from previous batch cannot be tolerated.
In addition to the obvious problems posed by subjecting consumers or patients to unintended contaminants, potential clinically significant synergistic interactions between pharmacologically active chemicals are a real concern.
2. Contamination with unintended materials or compounds
While inert ingredients used in drug products are generally recognized as safe for human consumption, the routine use, maintenance and cleaning of equipment's provide the potential contamination with such items as equipment parts, lubricants and chemical cleaning agents3. Microbiological contamination
Maintenance , cleaning and storage conditions may provide adventitious microorganisms with the opportunity to proliferate within the processing equipment.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Cleanroom Requirement
To translate the qualitative concept of “clean” to a
quantifiable parameters for environment control
,environment specification / classification is required.,environment specification / classification is required.
For classification we measure the suspended
contaminant density or numbers of suspended particles
per unit volume. The lower the contaminant density, the
cleaner the environment.
10. Definition
Cleanroom:[ISO 14644-1:1999, 2.1.1].
Room in which the concentration of airborne particles is controlled,
and which is constructed and used in a manner to minimize the
introduction, generation, and retention of particles inside the room,
and in which other relevant parameters, e.g. temperature, humidity,
and pressure, are controlled as necessaryand pressure, are controlled as necessary
Changing Room:
Room where people using a cleanroom may change into, or out of,
cleanroom apparels.
Airlock:
Intermediate room or area that is usually ventilated, and used to
minimise the transfer of airborne contamination from one area to
another
11. Definition

appropriate.appropriate.
Cross-over benches, garment and supply cabinets, lockers:
periodically empty and clean interiors and surfaces by wiping
Rubbish bins and containers
Rubbish bins and containers can be lined with plastic bags to remove the refuse and
protect container surfaces. All bins should be removed to general, non-critical areas
and remove the rubbish.
Cleanroom mats and sticky flooring:
Cleanroom mats and sticky flooring should be cleaned by wet mop or maintained on
a regular basis. Use vacuum cleaner as required.
31. Cleaning Frequency
Schedule / Frequency for cleaning:
Most routine cleaning operations should be performed as per established frequency
at regular basis. Other cleaning may require on certain frequency or when needed.
Daily cleaning (once in 24hours):
Clean room floors, walls, doors etc. Air locks, changing & operational areas should
be cleaned at least daily. Vacuuming and or mopping floors, and wiping the surfacesbe cleaned at least daily. Vacuuming and or mopping floors, and wiping the surfaces
Periodic cleaning
Surfaces not cleaned on a daily basis should be cleaned periodically like
weekly, bimonthly or monthly etc eg storage areas, service areas, pipes and fittings.
Intensive cleaning efforts should be taken after holidays or planned shutdowns
32. Non-routine Cleaning
Cleaning after modification, construction or maintenance
Effective cleaning after construction is essential to control and
eliminate contamination sources.
